Every summer, they come. They sneak through the windows and ravage your ankles; they find the one spot on your left shoulder that didn’t get drenched in a layer of DEET (God bless you, Deep Woods Off!) and gnaw, chomp, and suck away.

From May to September, many of us – covered in scars and bloody scabs, the remnants of these bites now gone bad – live side-by-side with people who, despite living in the same house and even sleeping in the same bed, are seemingly less vulnerable to the vicious six-legged predators. It turns out, a mosquito’s snacking preference for one person over another is not just a curious annoyance, it’s also a medical concern: Since malaria and other diseases are transmitted by bites, people who get bitten a lot are more likely to become ill. Because of this, researchers are working to find the mechanisms in mosquitoes that cause them to sniff out you, and not your neighbor.

Scientists have identified several proteins found in mosquitoes’ antennae and heads that latch on to chemical markers, or odorants, emitted from our skin. These markers are produced by the natural processes of our bodies and, like neon signs, they let the mosquitoes’ smell center know you’re around (though the process that then guides them to you is not well understood). Flies and mosquitoes share a number of the same genes that dictate production of these odorant-binding proteins, which have specific sites that will catch or bind with certain chemicals in the air. Some scientists suggest that certain characteristics attract mosquitoes, thereby leading us to have more bites than others. Some of the top candidates: the amount of carbon dioxide in the breath, pregnancy, body temperature, alcohol and odorant markers based on blood type.

Blood-type markers are chemicals released by people of a specific blood type – so if someone with AB blood emitted a marker, it would be different than that released by B. One study found persons with Type O blood suffered more mosquito landings because of the odorant markers they emit than any other blood type, making their juices a hot commodity for blood banks, as well as Asian Tiger Mosquitoes, which carry West Nile Virus. Not only were Type O’s more likely to be landed on, but the study found that for any blood type, people who secreted a chemical marker about their blood type through their skin (both blood type and secretor status are determined by genes) were bitten much more than non-secretors; 24 percent in the case of the Type O’s. Other researchers estimate about 15 percent of the population, based on their genes, don’t emit chemical markers of their blood type through their skin and saliva, so something else has to be calling the mosquitoes to them.

Pregnancy seems to be a big winner for mosquito attraction, probably because mothers-to-be exhale 21 percent more carbon dioxide (quite a turn-on to the six-legged species) and are on average 1.26 degrees Fahrenheit warmer around the belly than their non-pregnant counterparts, due to the temperature of amniotic fluid. Also, having just 12 ounces of beer increases your mosquito appeal, possibly because of the increase in body temperature it causes or because skin markers change when metabolizing cocktails – unfortunate since outdoor drinking is a highlight of summer anywhere.

One researcher suggested smell is unimportant, and what really matters to the mosquito currently chomping on your toe is not the smells you’re giving off, rather it’s finishing her meal without being swatted away. Because of this, she’s better off attacking “less defensive” animals, rather than more defensive, and so is evolutionarily predisposed to biting lazy or incapacitated prey (reference drinking above).

Infectious disease experts are anxious to solve the mosquito preference puzzle so they can design repellants tailored to vulnerable people, which would either block an individual’s smell signatures or disarm a mosquito’s scent receptors. Unfortunately, a specific answer to your skin-piercing question continues to itch away at scientists, and I suggest stocking up on bug repellant in the meantime.

  1. thank you for the article.now i can answer to some dumb people when they say i get bit by mosquitoes because of my body smell.i get so agravated!!!

  2. I just absolutely KNEW that frequency of bites had to do with blood type. I am type O and am ALWAYS getting eaten alive by mosquitos! Many of my friends that are type A NEVER get bitten, even when a mosquito lands on them!

    Jessica, July 17, 2008 at 6:49 pm
  3. Erm… I’m an O and I never get bitten!!

    Ritu, July 20, 2008 at 9:57 am
  4. My blood type is a+ and I am always getting bitten. I think it’s because I am so sweet. LOL

    paula, July 21, 2008 at 1:24 am
  5. I have a real problem with mosquitoes biting at my bag, is it possible my bag emits an odor that attracts mosquitoes?

    LOL this thread is messed. Mosquitoes bite people to live and feed their young, the numbers mean nothing and I would have to go with the chaos theory, in that someone has to be bit more than another and someone has to be bit less, otherwise the world would explode without randomness, or chaos.

    Wanna learn something that pertains to everything, check out chaos theory. Stats are pointless.

    Mike, July 23, 2008 at 9:17 pm
  6. Interesting, but my family totally blows the blood type theory. I have a daughter who is B+ who absolutely gets eaten alive and one who is A+ with a pretty strong attreaction. The rest of us who are A+ and O+ use the first two as our repellent.

    Liza, July 24, 2008 at 9:46 pm
  7. Last year i went on holiday, my brother aged 10 and my son aged 4 shared the same room my brother got bitten loads with repellent on and yet my son didn’t get one bite we used repellent on him the first couple of days, but after that he didn’t have any on as they didn’t seem to like him and he still didn’t get bitten. Im just intriged to know why???

    kelly, August 1, 2008 at 5:23 am
  8. Always knew it must be linked to blood type, not sure on the O type though, Im A- and always get bitten alive while no-one else does!!???

    Karen, August 1, 2008 at 12:55 pm
  9. Thank you for this article. now i have an answer to why mosquitoes bite me all the time instead of the other people in the same room as me. it’s only because of my rich thick blood type! and because of bodyly secretions that i give off. and my smell, and a whole lot of other things. thanks!

    Lexi, August 6, 2008 at 12:23 pm
  10. how about this…when i get bit by mosquitoes, which not only seems to be more than everyone i know, i get bitten in quick clusters. i don’t just get one generic bite here and there. i will get bit in repeated succession in a big cluster of sometimes four or five bites in a small area. no matter where i go, this holds true.

    Angel, August 8, 2008 at 3:55 am
  11. i am type O and i never get bit. i don’t think i’m buying the blood type theory. there are posts here of people all over the blood type spectrum and their experiences are just as widely ranged.

    renae, August 18, 2008 at 2:29 pm
  12. OMGGGGGG!!!!!!!!!!!!!!!!!
    I GET BITTEN BY mosquito all the time, and i have no idea what my blood type is.

    Katoni, August 31, 2008 at 12:48 am
  13. I am type O and get eaten alive even with repellant on. I also have a blood disease called ITP, and I wonder if they like me because my blood does not clot normally.

    Susan, September 2, 2008 at 11:00 am
  14. Interesting…but the photo above the article is not that of a mosquito but a (harmless) crane fly. it would be hard to bite someone, regardless of blood type, without a nice long proboscis (nasty bitey part).

    SH, September 6, 2008 at 1:31 pm
  15. I am blood type B+ and have been attacked by mosquitoes continuously all of my 70 plus years. I have applied many different types of repellants but as of yet have not found one that works well. I have attracted them in the American continent all areas and also in Asia. I am resigned to being bit as there isn’t much I can do about it, hopefully sience will discover the reason and develope a repellant.

    Bill Clark, September 15, 2008 at 10:55 am
  16. This information I just read is right. I have never been bitten by mosquitoes But now i have been drinking a couple of beers in the afternoon and I go out and i get bitten within minutes at least in four different places uncles ,elbows and ,knees .When I drank red wine it never happen

    Tony Radman, September 17, 2008 at 1:43 pm
  17. I am AB+ blood type and Im bitten by mosquitos ALL THE TIME! Im just so sick of it!! Even the repellants dont help me! Its terrible.
    However, besides the blood type, the article states that the body warmth and alcohoc composition are also factors of attraction! :(
    Thank you for the article!

    Ady, September 17, 2008 at 10:11 pm
  18. blood type? what about body temperature? I have a normal body temporature of 96.3sih rather then 98.6 and i never seem to get bit. might not this be the major factor? warmer people get bit and cooler people don’t….Possible?

    Galen, September 25, 2008 at 8:58 pm
  19. One thing the article mentioned is that not everyone emits the scent of their blood type. Which would explain why some people with a certain blood type get bitten and some don’t – they don’t excrete the scent.

    I get bitten constantly. My mom does too. On a recent vacation to a lake house I was outside just as frequently as 2 friends and my husband (who threatened to put me in a bubble!) – we all drank the same amount, wore bug spray, and were even using the same shampoo and soap. I went in every night covered in bites, while everyone else was untouched; including, luckily, my son.

    It is obnoxious. We just killed one in the house – it bit me 5 times before we could get it. Grrr…

    Body temp is interesting – I have a low body temperature of around 96.7, and I don’t remember bites being much of a problem when I was pregnant.

    Thanks for the article!

  20. I live in a hot country and being constantly bitten is getting me down quite a lot.
    I now wear repellent every day and carry it with me. When i arrived 3 months ago i ended up scratching so much that the bumps and itching came up all over my arms and legs and stomach. It seemed like an allergic reaction to the bites but the doctor didn’t seem sure what had caused it. She said it was a food allergy or an allergic reaction to the bites. I think it was the latter.
    I have A type blood so that blood theory seems a bit off to me. My partner doesn’t get bitten very often, just now and then. Also my daughter gets quite a lot but not my son. Is it the female hormones that maybe attract them more or what?? The biggest annoyance is that i’ve been wearing trousers lately and get bitten on my legs so how the heck are they getting up my legs. I despise mosquitos. Why can’t they become extinct??

    Andrea, October 7, 2008 at 8:00 am
  21. I’m type O and used to get bitten a lot. Now that i’m older, i don’t get bitten as much. As it’s stated, 15 percent don’t emit the blood marker. But from what i’ve learnt, mosquitos are attracted to CO2 as well. So people that never get bit either don’t emit much CO2 or a blood marker or are move enough to keep them off.
    It states that type O are bitten more, but that could be the marker is more familiar as there’s more O around and is the oldest type.
    People that aren’t O but get bitten a lot, it could be you give off more CO2, emitted a higher blood marker or just really unlucky. I think i get bitten less because i weigh a lot more and my diet’s changed.

  22. My wife and myself plus my sister in law and her husband have just returned from playa del carmen in Mexico. My wife and her sister are twins and have the same blood group as myself (A+). I have over 40 bites and my sister in law in excess of 30, my wife had NONE and my BIL 3 which were barely noticeable. In terms of alcohol my BIL drinks more than all of us and is blood group (O).

    I can’t comment on carbon dioxide levels but an certainly say neither my wife or SIl are pregnant … in short i’m none teh wiser just very itchy

    Mike, October 14, 2008 at 2:47 pm
  23. I live in Thailand and am relatively unaffected by mosquitoes – I notice though that most of my friends who are, take ineffective precautions. They claim all sorts of reasons and then go out in the evening in short sleeved shirts and no socks.
    They become obsessed with ridding a room of mosquitoes and then sleep without bedsheets……

    wilko, October 19, 2008 at 9:37 pm
  24. odorant marker emmited from the blood type..interesting..i always wondering why my mother’s always gets bitten instead of my father.. my mom always says that she has a sweeter blood than my father cause she’s the only one gets bitten.. but based on temperature it’s kind of opposite cause my father’s body temperature is higher than my mother ..

    ojyou, November 17, 2008 at 8:46 am
  25. I am blood type AB+ and prior to having a kidney transplant didn’t have any major issues with mosquitoes. Since the transplant and the immunosuppresion medication i take, I now have a huge problem with being bitten and also how much they itch. The itching becomes almost unbearable and as someone else commented I now get bitten in clusters of about 5 or 6 bites at a time. It would appear that mosquitoes are definitely attracted/deterred by different odors, otherwise repellents wouldn’t work. I know that since the transplant I have had some hormonal changes so I’m guessing their attraction to some and not others could be to do with hormone’s and their affect on our bodies

  26. my experience is different then anyone else!!!
    infrared radiation of body is more likely. I don’t know if you noticed but they bite rite on the veins. closer the surface. sounds more logical as well. other reason they fly closer to ear lopes at night. one more observation is they use ear drum as speaker and radar they bounce their wing noise find their way like bats.

    anyone to test these?
    let me know. email haluk@bosspacific.com.au

    haluk yildirim, December 9, 2008 at 5:07 pm
  27. I have a+ blood so does my son. I never get bitten, my son gets covered from head to toe in bites and where there are no bites there are scars from last years bites, he is constantly uncomfortable and itchy. I completely disagree with the blood type theory. I agree with the explanation that we are all bitten, but only some of us react negatively. I beleive those that are already predispositioned to things like asthma eczma and allergies are more prone to have an overeactive immune system that may cause these small bites to become irritated.

    serina cole, February 4, 2009 at 12:57 am
  28. Over the last two nights my partner and I have been unidated with the pesty Mozzies, my partner who is A blood type has been bited 13 times in the last two nights and I being O+ have no had not one single bite. So that blows the theory about blood group O is bited often than other’s?

    Melissa, February 10, 2009 at 10:38 pm
  29. So, what are scientists waiting for to find out
    what the mysterious secreted scent is that attracts
    these nuisance bugs?
    This isn’t rocket science!

    JD, February 16, 2009 at 6:52 am
  30. I think this is all very interesting – because my personal experiences are the opposite to the article. I am 30 and British and now live in South China where mosquitos are rife. I am O- blood type, I drink alcohol, and eat cheese…but I never get bitten (touch wood). My poor Chinese girlfriend on the other hand is A+, doesn’t drink alcohol or eat cheese but gets bitten all the time – to the point she is left with swellings and bruises. More research is required here I think. And yes, you would think this would be straight forward enough for scientists…

    JEP, March 22, 2009 at 1:06 am
  31. oh by the way serena, my girlfriend has no other allergies or asthma etc but still gets bad seriously bad reactions to the bites…

    JEP, March 22, 2009 at 1:10 am
  32. Mmmm…. I don’t think it has anything to do with blood type. I am Asian with AB+ blood type and I get eaten alive!! If I am with a group of 10 people, the mosquitoes will still find me! More research is needed. I usually don’t go out after dawn….

    Pinkie, April 16, 2009 at 8:57 pm
  33. Since I started to take Simvastin tablets 2 years ago to reduce cholestrol I notice that in the aerly part of the year March-may I get bitten regularly and generally have about 3 to 5 bites on the go at any one time.
    before I took these tables I rarely got bitten and generally once the damp season is over by June I am okay.
    I really don’t know what to do to stop them,even when I tuck my socks into my trousers if I go out into the garden they seem to get up my trousers.

    Malc, April 17, 2009 at 11:53 am
  34. I was biten all over yesterday.
    The strange is, when I was in Asia, I was never bitten and now I’m back in Europe, the second day I had like 150 bites.

    Sander, April 19, 2009 at 2:25 pm
  35. why is it mosquitoes more attracted to type O blood group people? any scientific evidence please?

    ammy, April 27, 2009 at 3:56 am
  36. Hi I am a 57yr old woman and as for as long as I can remember I have been been bitten by mosq. I am sitting here with numerous bites and I wasn’t outside!! We have a whole house fan and opened the windows(screens) and I got bitten!! I am type 0+ and I also have ITP.
    My husband never gets bitten…I found out I am also allergic to mosq. so the itch is unbearable!! I am frustrated to say the least.

    Linda, May 2, 2009 at 10:14 am
  37. I agree with the temperature idea in this article. I have such a low body temperature I hate air conditioners. I can’t remember the last time I was bitten, though people around me seem to be magnets for mosquitoes.

    Ramone, May 9, 2009 at 4:27 pm
  38. Didn’t really care til I went to the beach with my girlfriend and wanted to sleep under the stars with a comfortor and pillows in the bed of my truck. No bug spray was used because we didn’t think of it.

    I got destroyed by mosquitos! I probably got bit 50-75 times and my girlfriend got bit maybe twice. While I was wrapped up like a mummy sweating, she was next to me with her leg out of the covers to cool off. She thought I was crazy til she saw the welps the next day.

    we’re both A+

    Daniel, May 18, 2009 at 10:56 am
  39. omg I am A+ and I get eaten alive. I just walked out the door just now and got bit six times within less than 10mins. My husband has O+ and he never get’s bit. My legs and arms look like I was stung by a bee instead of a musquito. I hate them so much.

    Charlene, May 22, 2009 at 7:10 pm
  40. I’m a professional statistician and I feel a need to clear some things up.

    There is a probably a correlation between having type O blood type and getting more mosquito bytes, but as I’m sure you’ve all heard, correlation does not equal causation. This is an example of confounding with odorant markers, which are associated with both the outcome (more bites) and the predictor (blood type) and differentially distributed between the levels of predictor. Though having type O blood may not in and of itself be reason for a mosquito to choose one person over another, type O blood *is* more often observed in the “secretors” that mosquitos prefer.

    I’d hypothesize that in an experiment where odorant levels are controlled, the relationship between blood type and bite predisposition would vanish. However, you can say that on a population-wide level, knowing a person has type O blood makes them more likely to be a mosquito magnet, inasmuch as it makes them more likely to have the genes for giving off a mosquito-friendly scent.

    topher, May 25, 2009 at 12:44 pm
  41. I am type O+ and was only outside for an hour today and got bitten 13 times. Mosquitoes just love me and it is annoying. Every year I get so many scars from these nasty blood suckers because I itch them so bad. I think it is because my blood type. Everyone I know only get bitten every once and a while and none of them have type O blood like me.

    Lindy, May 26, 2009 at 12:15 am
  42. Since becoming a raw food vegan mosquitoes don’t touch me like they did in the past, has there been any studies on the correlation between mosquito biting & blood purity or cleanliness??

    ChrisT, May 29, 2009 at 10:07 pm
  43. ugh,as im reading this both of my feet are swelling b/c i got bit on the toes and around the house too!… does that mean im allergic???

    Rosan, June 1, 2009 at 12:29 am
  44. the last few weekends we’ve had outdoor dinners w friends. I’ve been bitten over a dozen times each night. The three others are usually not bitten at all, or may have one or two. Blood type or something else… this has been happening to me for years.

    michael, June 2, 2009 at 7:31 pm
  45. Hi, I get bitten all the time and very badly. Abroad or at home. The only repellent that I have found good is avon skin so fresh – woodland fresh. I have used it in USA, UAE and all over the world. So long as I am wearing it head to toe I am ok!! With out it I have been admitted to hospital as I react very badly!!! I only hope it continues to work for me!!

    Heather Lavery, June 7, 2009 at 8:01 am
  46. I think that a mosquitoes only bite you when you are in the shade, if you are in the sun they can not see you beacuse you blend in with the heated suroundings.
    I think they see heat, like in the movie preditor, he did not see Arnold as a human but as heat while in a shaded forrest but as soon as Arnold covered himself with the cool wet mud then the preditor could no longer see him.
    I don’t know for sure but this is my think on how they pick you out and heat among a cool back drop says food to them.

    Jo-el, June 10, 2009 at 3:48 pm
  47. Well, anyone notice that the insect used for the picture on this article is actually a Mayfly? I get bit a lot! can’t a gene specialist create a strain of Mosquitos that all of the sudden mutate and have no wings after several generations? Seems like beter use of gene studies, ridding the planet of Mosquitos would solve a lot of infectious diseases.

    Forrest, June 11, 2009 at 1:36 pm
  48. I went to Southern Maryland last summer and I got bitten so bad. I had about 20 bites on each leg and a whole lot of random ones all over my body. I just came back from Cape May, NJ and I am bit up again. Not quite as bad but I have about 7 or so on my legs and ankles, some around my neck and ears and some other random ones. I am not sure of my blood type but I wish I knew why these things bite the hell out of me. My boyfriend was with me at both places, doesn’t even put bug spray on and only gets like 1 or 2 bites total. Here I am scratching like crazy. I don’t understand and I am honestly quite sick of these damn bugs biting me so much. I wish I knew what the reason was. I don’t wear perfume when I’m outside in the spring or summer cuz that makes it worse. I was told to swallow a matchhead before going outdoors in areas I might get bitten.

    Stephanie, June 13, 2009 at 2:51 am
  49. My husband and I can be sleeping on the same bed or be in the same vecinity as a mosquito and they never bite him: They feast on me! I jokingly tell him its my sweet blood they’re after. I have O+ blood, I’m not sure what my husband has.

    Mary, June 15, 2009 at 2:09 pm
  50. All this thing about blood group and CO2 etc is bull crap . Just read the comments and you can tell – these are not common factors among the people who get bitten.
    If you have been doing bad things, God sends mosquitos to leech you. Thats right – its a punishment plain and simple.
    If not , you are spared – how difficult is that to understand ?
    Long story short – do good deeds that will please God, and he will in time direct the mosquitoes to the bad guys.

    Mosq Guru, June 26, 2009 at 3:02 pm
  51. I am a white make 53 years old, my sister is 1 year younger, since we were small children we have not been bothered by mosquitos, my father was also not bothered by them durnig his life. One intersting note is that all three of us have/had blood type O negetive, while my mother who had A (I think) blood was constantly being eaten up by them, this isn’t just that they don’t bother me much, I mean that they don’t bite me at all, maybe twice in 3 or 4 years.

    William Pike, June 27, 2009 at 8:25 pm
  52. I really don’t get it…I am an 0- i will be the first person to get bit all the time but my brother in law is an A and he NEVER EVER gets bit..and when he does the 1 mosquito that bit him ends up just flying away after 1 sip! They just keep suckin away on me until I have a bit the size of a half doller coin of course. There really bad can anybody help me with any suggestions..I put on OFF sport for waterproof and sweat proof and that really doesn’t work eather….

    Jamie, June 29, 2009 at 7:59 am
  53. I’m a redhead with fair skin. I’m also a bit heavy. Mosquitos ALWAYS target me. As soon as it is dusk – I’m toast! Right now I have about 20 bites from working in the yard. It’s the most I have ever had and it’s sooo itchy!

    Mel, July 4, 2009 at 11:35 pm
  54. I am Blood type O+ and I seldom get bit. If I get 5 a summer that is a lot.

    Mary, July 5, 2009 at 11:21 pm
  55. im O- and never get bitten. they will land on me and then fly to the next person. i dont even own a can of mosquito spray. i wonder if it has more to do with what foods we eat and how our bodies digest it? you are what you eat right? mabe some blood is less desireable to them.

    sasha, July 6, 2009 at 10:50 pm
  56. I’m 30, pregnant and have type A+ blood. Ever since I was a little kid, I’ve been the only one who ever gets bothered by mosquitos and, even more horribly, no-see-ums. I was pregnant with my daughter in the summer of 2007 and counted over 60 no-see-um bites on my left leg alone–and I also have immune system problems…so these bites were ten times worse than the two my son had and the one my husband had. Ugh, I hate bugs and the itching and scratching and burning feeling they leave me with. I have scars ALL OVER my body from childhood and adulthood from scratching the bites until they bled and then scratching at those because they still itched. :((((( HELP!

    Dawn KILIC, July 7, 2009 at 11:26 am
  57. Im A+ blood i get bit so much right now i have 57 i counted the most ive had is 88 i use bug spray but it dosent work and this happens every year since i remember im only 15 so hopfully u can find a way 2 stop this

    Rory Scanlan, July 8, 2009 at 12:14 am
  58. quoting Sasha from July 6, >>I’m the same way they will land on me and kind of sniff around and then fly off, occasionaly one will try to bite and sort of gets stuck, I’ll reach down and wipe her away, never get any kind of bump or mark from it.

    William Pike, July 8, 2009 at 11:01 pm
  59. I am blood type A, I get eaten alive by mosquitos whereever I go. In the Caribbean I got pretty large watery blisters and intense itching. I will never go back there. I had on repellant, mosquito netting over the bed, tooks loads of the vitamin Thiamine, burned mosquito coils under the bed and on both nightstands and they still bit me. I just got back from Redding, CA and they aren’t nice ones up there either. I’m still itching a week after I was biten 9 times. I got watery blisters from those bites also but only half as bad as Antigua, St. Vincent and Bequia. Eash island seemed to get worse and it was actually making me sick. It wasn’t even mosquito season! I have found that if I can apply Witch Hazel on a cotton ball as soon as I am bitten that it helps a great deal.

    Sami, July 13, 2009 at 7:18 pm
  60. By the way, my boyfriend is an “O”. They hardly touched him and if they did he had only minor irritation that didn’t last more than an hour or two. He had no repellant on at any time to try to keep them from me but it did not work at all.

    Sami, July 13, 2009 at 7:23 pm
  61. I’m just rereading these things and other than the few crazies it seems that you are all saying that the Positive blood type(both O and A) people are being eaten, as opposed to the Negatives. Can that be the link?

    Sami, July 13, 2009 at 7:31 pm
  62. Such sad posts. I’m B+, get eaten alive and in clusters if I spend more than two minutes in my front yard. No one else is affected. Other family members = three O+. Years ago a landscaper told me to take garlic capsules. They work wonderfully. Just started taking them for this season and can’t wait for the effect to kick-in. Scratching now,

    G Clark, July 14, 2009 at 5:31 pm
  63. Too bad there is no easy explanation. I have O- blood, so that theory is fun to entertain, but for half my life I was not at all bothered by mosquitoes, now I am their favorite food source. I spent the day at Sunrise in Mt Rainier National park yesterday and was covered with bites that, again, swell and welt, my hands and toes were swollen. They bite regardless of what I put on or wear. The allergic reaction I get is a bit frightening, I actually got a cold shiver after one set of bites. I am worried about what is happening, on one camping trip I had so many bites that would not come out of the camper and took antihistamines to counter the hives and chills. This used to never happen, and I usually camp in a tent, and have for years. It is like thing flipped a switch in my and I have become bait. I was not drinking anything but water, my diet (good, healthy) has not changed. I am carrying a bit more weight than I did as a teen or a twenty-something, and after 2 pregnancies I have not the same weight as I once did. There was a difference after having 2 children in how many mosquito bites I got (lots more). But now, I am in the middle of the mosquito’s radar zone.

    Elizabeth, July 17, 2009 at 1:10 pm
  64. I am also A- and always get bitten more than any of my o Positive relatives, More study needs to be done!!!!!!!!!!

    deb, July 18, 2009 at 8:39 pm
  65. A positive and I almost NEVER get bitten.

    There must be something to this blood type stuff.

    Tailgunner, July 22, 2009 at 1:42 am
  66. I live in the Philipines with my brother. He is blood type O the same as me.
    We eat the same food and drink the same types of alcohol.
    I have never been bitten in my life but my brother is a target. I believe there is something in my blood which deters the mosquitos. I have watched one land on me and immediately take off probably heading towards my brother!!

    bob potter, July 22, 2009 at 6:32 am
  67. question for Elizabeeth, you said that the first half of your life you were never bitten, now you are their favorite food, at what age did this change, and were you pregnate? my sister’s imunity changed with her first pregnancy.

    William Pike, July 26, 2009 at 9:42 am
  68. I am blood type A+ and get bitten really bad, the only thing that somewhat helps me is Avons “skin-so-soft” and even that wears off after a while. Ny husband’s type is O- and he rarely gets a bite. These seem two be two ends of the spectrum that mosquitoes either attack or dont. I guess theres no set pattern

    Kat, July 26, 2009 at 11:57 pm
  69. Mosquitoes used to bother me tremendously. The bites produced the standard welts, and itched like crazy.

    After spending about 15 years as a Conservation Officer in Michigan’s Upper Peninsula – with LOTS of mosquito bites – I realized that I no longer got any bites. For the rest of my career, I was bite free.

    Even now, 12 years after retirement, I have an immunity. They still buzz around me. On occasion, I will feel a very slight stinging sensation, as one starts to bite me. They never complete their meal, but fly off after just starting to bite.

    Palod, August 2, 2009 at 7:14 am
  70. I bet people who get laid more get bit less. Mosquitoes can feel that tension

    ZorkDude, August 10, 2009 at 9:19 pm
  71. Hot blooded O+ type scratching the heck out of myself at the moment, looking for a dang cure. Can I deposit my blood at a blood bank and ask for a different currency? I don’t care if the exchange rate kills me, this is insane! I don

    Ben, August 13, 2009 at 6:39 pm
  72. if you have the o blood type the only reason wny they come after you is becuse thay cant resist is because it tastes so good to them.

    Alexander, August 14, 2009 at 10:26 pm
  73. this kind of explains a lot. im leaning more towards the chaos theory though. i believe randomness is essential to order.

    charles patrick, August 21, 2009 at 9:20 am
  74. I just wondered is it because o type blood can be given to most blood types and is a common to all. I am O possitive and I am alway bitten and even by the irish flys from end of augst, Help needed.

    Ethel, August 22, 2009 at 12:19 pm
  75. my whole family is type o blood, but for some reason i always get bitten the most and have a minimum of 30 bug bites on me at all times during the summer. they usually center around my ankles and feet, i guess i just happened to be the one who got the most delicious combination of genes in the family…

    constance, August 25, 2009 at 12:44 pm
  76. I have always thought something to do with blood. I am A-, so was my Dad; rest of family +. He and I always bitten, others not. My theory has been that is to with the negative bit rather than whether A, AB, O etc. Not only do I always get bitten, but I am allergic to the bites and always get infection, cellulitis, allergic reaction bordering on anaphalaxis – last time ended up on a drip for 24 hours!

    Marion Hughes, August 26, 2009 at 5:54 am
  77. I’m blood type A and get absolutely chewed on; my wife is an O and the little buggers don’t even seem to know she’s around.
    I was under the impression the heat signature you put out affects how mosquito’s “see” you.
    She’s ALWAYS cold, but I put out a tonne of BTU’s.
    The house could be on fire and she’d be putting on a sweater – I’m happy in a -30 blizzard.
    But then there’s no mosquito’s around then.

    Ed, September 1, 2009 at 3:10 pm
  78. My husband is type O and the mosquitos don’t pay any attention to him. They go straight for me, type A. Could it be the secretor? I should get that checked.

    Kathy, September 1, 2009 at 6:45 pm
  79. I am blood type O and get bitten like crazy. I just had to speak with someone out in the yard, I was immediately attacked by mosquitoes and ended up cutting our conversation short because of the mosquitoes. The man I was talking with did not get bitten. Now have about 30 bites all over from just 15 minutes outside! I put on repellent in the morning but don’t always remember to reapply it until after I am attacked. I was once told that taking B vitamins would stop them from biting you, but I tried it, and actually I still take B vitamins and still get bitten like crazy. I am interested in the garlic capsules. I already take one garlic capsule a day, if I took more I wonder if it would help? Also would it have to be non-de-odorized garlic?

    Jules, September 2, 2009 at 7:39 pm
  80. i kno how yall feel. i have nooo idea what blood type i am but all i kno is that everyday, i HAVE to get bitten by a freakin mosquito. my problem is i walk a lot but, just when i get to my house, i get bit.i wear shorts that go to my knees so how do the dang pests get up to my thighs? heres my solution,not much help but it works……..ish: get skin cream and rub it on you after you get bit, it should help a littli and try to control your itching, the more you itch the more the bite gets bigger and itchier. the only thing we can hope for is that in a few million years, the world will end and mosquitos will be gone (just be sure you have an spf of 1000000 for sunscreen,your gonna need it)

    Elana, September 10, 2009 at 9:46 pm
  81. I am A+ and get bitten all of the time. I get quarter to half dollar sized whelps with each one. I have found that putting ice on the bite helps. It reduces the swelling and thus the itching. If you can keep from breaking the skin on the bite it will heal much faster.

    Peggy, September 24, 2009 at 12:32 pm
  82. AH! I have type O blood and I will be the ONLY person in a group that gets bitten! Everyone thinks I’m whiny because they don’t seem to be getting bites. Mosquitos and fleas have ruined the appearance of my legs forever. I hate the smell of deet. I wish there was another way! Thanks for the info.

    Becky, September 24, 2009 at 7:28 pm
  83. If mosquitos are attracted to CO2 or people who exhale more CO2, and if “thinking” cause the brain to use up more 02 and give out more CO2, then “thinking” may be the key to mosquito bites?

    yubing, October 10, 2009 at 7:08 pm
  84. this is alot lol (:

    jennifer, October 23, 2009 at 5:43 pm
  85. im heela bored ):

    jennifer, October 23, 2009 at 5:44 pm
  86. I never get bit, but i always have a good laugh at everyone else that does. I can be camping, at a bbq, ballgame, it doesn’t matter, I just don’t get bit. My wife gets eaten alive, even when she uses repellent. I don’t use repellent, cuz I DON’T GET BIT. For all you bite sufferers, let me just tell you how nice it is to never have to worry about mosquitos. sorry, but I just love to rub it in.

    trade, October 24, 2009 at 11:44 pm
  87. Ugh seriously, I am type O and every time I step outside my arms get all their blood sucked out! I don’t know anyone who gets worse bites than me. It’s funny though because I’m so good at ignoring it that it doesn’t even bother me, and if it does get the occasional agitation, it feels good scratching them!!

    D.Jay, October 27, 2009 at 10:34 am
  88. The funniest part of the whole article is the photo. The pictured insect is not a mosquito (Culicidae) but a crane fly (Tipulidae), and these do not bite at all.

    Hopper, November 1, 2009 at 11:01 am
  89. I am an O Blood type, I drink beer and never try to kill them…so Im pretty well the prime candidate. I sat outside one night after work with a beer in 20 minute I got 26 bites on my back, the other two outside didnt get bitten at all.

    Cheri, November 16, 2009 at 8:02 am
  90. I’m AB-, usually have a 97.2 body temperature. My 8 siblings have the same blood and temp. None of us ever got bitten by mosquitos, despite living in mosquito laden Michigan woodland area. Our parents are bitten at a normal rate. ALL of the 24 grandchildren of various blood types are bitten at a high rate, several requiring medical care after campouts, etc.

    Until I went to nutritionist and my diet changed from almost exclusively meat, milk, and junk food to one containing whole grains, fruits, and vegetables. Since my diet change in 2006 I have been bitten several times each year, and this summer (2009) I was bitten 7 times, and the sites got itchy and red. That never happened before.

    Hormones? Age? Inheretted immunity, then acquired intolerance?

    I blame the vegetables.

    Sue, November 22, 2009 at 1:42 pm
  91. I’m 13. I’m type AB and I had gotten bitten all over my arms and legs when i was smaller so much, that i went to the doctor once{around 10 or 11 years old} . it was itching horribly. my mother even went as far as repeatedly changing my bed sheets because this happened over night. She bought a spray and sprayed me with it. It was to repel against the mosquito. I still experience getting bitten a lot. It’s quite annoying.

    alexia, November 29, 2009 at 3:20 am
  92. I never get just one bite. Usually more that 5-7 and then they come back for more and bite up to 11 times. these are the “normal” times i get bitten. Like I stated above, I went as far as seeing a doctor because my arms and legs we full of bites. If I showed someone, they would freak out. I’m honestly fed up. I’m writing this now because I’m experiencing the itching on my legs and hands as I type this.

    alexia, November 29, 2009 at 3:26 am
  93. The picture given is not that of a mosquito! It’s a crane fly (Tipulidae)

    P K Sumodan, December 14, 2009 at 10:50 am
  94. I am a researcher working in an unrelated area; however,the above discussion seemed very interesting to me. I am just wondering if anyone has looked at the concentration of the specific protein types in the blood that mosquitoes are looking for and the number of bites. Thanks for the article and everyone’s comments.

    Chowdhary, January 8, 2010 at 6:17 pm
  95. thank you for a wonderful article. now my colleague and I are aware about mosquito bite in general

    prito, January 27, 2010 at 3:42 am
  96. thank you for a wonderful article. now my colleague and I are aware about mosquito bite in general. that what an awesome information that could help my topic.

    prito, January 27, 2010 at 3:43 am
  97. Interesting post, I’m an ‘O’ and I rarely ever get bit. Never thought about it much before though.

    mosquito traps, January 27, 2010 at 9:57 pm
  98. for years and years every time i go camping im the ONLY one who gets eaten by thos damn bugs .When i was 10 are atv got stuck 10k away from help and we had to walk all the way there . my back was covered in bits and the sad part is they had to bite thru jacket

    Eaten alive, January 31, 2010 at 10:38 pm
  99. I’m B+ 56-year-old female and hardly ever get bitten, although I used to when I was younger. I live in climate where mosquitoes are prevalent except in winter.

    DebH, February 5, 2010 at 4:52 pm
  100. There seems to be very little pattern with blood type on the above posts….many of you do not note whether you are rhesus negative or not? Maybe this makes some difference too? I also think it is dependant on the type of mosquito…has to be! I rarely get bitten in Europe but on a recent trip to Egypt I got eaten alive – over 100 bites over two evenings (in clusters) and my four friends had around ten bites between them all!!! I am B- blood type. Wish they could eliminate the world of these little pests!

    LynseyC, February 26, 2010 at 7:35 am
  101. Just another random thought about body temp…… apparently the colder we are in body temp the less we get bitten….the colder I am the more I wear…hence less skin exposed to these nasty little blood suckers…hence less bites? No? People who have raised body temps would be inclined to wear less. Not a scientific fact… more like common sense :)

    LynseyC, February 26, 2010 at 7:41 am
  102. I am O- and mosquitos could not be less interested in me. I am grateful to not have to wear bug spray all the time. I do know I have very good oxygen uptake. This may help. It would be nice to know why I’m so lucky, maybe diet or vitamins? I keep up on my vitamin Bs…. I have been to the Yucatan, Bahamas, Virginia and the Mid-west in the summer, and all up and down the West Coast. It is so rare that I get bit in any of these places. I did get bit as a child though.

    Chelsea, March 1, 2010 at 11:05 am
  103. I thought as Marion post 76 that it may be to do with the Rh factor rather that the blood type. I am A- and never get bitten. She is A- and attracts mosquitos, so that theory is out the window.

    Noelene, March 13, 2010 at 6:36 am
  104. It seems blood type and Rh doesn’t matter.

    There is a wide range of reactions such as multiple bites, cluster bites (that would be me); very large welts indicative of a stronger reaction to the mosquito “saliva” (me again) vs. those who get garden variety itchy bites; and those who even are bitten through clothing (me again).

    I live in Maryland about a mile from the bay and have already fed more than a few mosquitos on just one 30-minute power walk at 6 pm yesterday (so movement doesn’t deter them from biting) after an unusually cold winter and snowy/wet couple of months with lots of snow melt and standing water.

    Garlic may interfere with the host scent as some have expressed.

    And some of us experience something midlife that changes are bite frequency too.

    Replentents work, and sometimes not. hmmmmm…. I wonder if it might be the strain or species of mosquito that is the key. Could it be that some strains of mosquitoes indigenous to an area go after some people, but not others? And that repellents are ineffective against some strains, but not others?

    Aveeno baths, hydrocortison creams, ice packs, and benadryl make up my drug store list from March through late October for me every year….

    kefirah, March 17, 2010 at 4:44 pm
  105. I don’t know what blood type i am because i don’t like needles, i get bits around my leg area more than anywhere else does this mean anything? thank you!

    Arwel Jones, March 21, 2010 at 4:10 pm
  106. I do not know my blood type but i know that my mum is O- and my dad is O positive and they dont get bitten at all!
    No mosquito creams work for me and i can’t take tablets so i don’t know what to do about these annoying lumps!
    All the comments are defing all the articles i’ve seen and I just wish there was a logical explanation!

    Please help.

    Em, April 3, 2010 at 5:48 am
  107. my honey is o neg, he never gets bit…. I and my 4 children all are o pos..we get eaten alive…you do the math…we are delicious

    Shannon, April 17, 2010 at 2:54 pm
  108. I am Rabindra Chauhan from India, my Blood group is AB+ and I am always sucked by mosquitos, to be frank I was in the search such article or research so that I can know the real problem. No other of friends are really get mosquito bites as me. Please publish some exclusive report on AB+ group…Thank You

    Rabindra Chauhan, May 16, 2010 at 11:04 pm
  109. okey let me use some common sense here.. I’m in the army and we are deployed to Iraq and I been bitten a lot by mosquitos here they are big and they are a lot so I know about mosquitos trust me when I say… I’m pretty sure that hydration has a lot to do with this mosquitos’s radar.. meaning they find you easier and more exquisite you more than other people in the same room… If you analize this and compare the information that has been researched by the scientists so far and common sense we can make up a reasonable explanation since they are inconclusive on the reason why some people get bitten by mosquitos more that others.. here in Iraq I have been drinking so much water than I can remember so I sweat more than when I was in the states !!! and when you are hydrated you sweat more than when you are not…heat has nothing to do with moskitoes finding you they don’t have heat sensitive goggles. Its you! is the water in your body evaporating. been hotter makes you sweat or evaporate your body water and with the water goes all that the researchers say too.. CHEMICAL MARKERS goes faster when you are hydrated and hot than a person with less body water and cooler than you.. if you are the only food in the room that ca detected, guess what? you gonna be eatten!!! does that make sense to you? okey…if that doesn’t I’ll give you this other escenario on how you can be conspicuous by mosquitos… put your sweat pants and sweter and go running at night, make sure you are well hydrated and the temperature outside is not hot. the colder the better and stop in front of a car with the head lights on… you gonna see your skin like a wet and hot towel taken out of a microwave. If you have another person do this so you can see it from a couple of feet will work better, have that person stand between you and the car with the headlights on. this is what moskitoes smell!! I don’t think is your cologne or perfume, axe body spray or victoria secret body spray neither

    junior, May 23, 2010 at 7:05 am
  110. If any body at a university wants to really use this theory and do the actual research and then get back at me with results but I really think this is the best explanation for the dilemma. Yunior_754@hotmail

    junior, May 23, 2010 at 7:14 am
  111. do not send any coments about my spelling I know it sucks… and i know how to spell mosquito I just like to write it like that moskitoes so yeahh the water in you and your blood type it is… if you are type O and don’t get bit by those try when your body is fully hydrated and you have eatten something delicious for them then get back to me on the result.

    junior, May 23, 2010 at 7:40 am
  112. I do not believe that blood type has ANYTHING to do with getting bitten. I am A+ and get bitten all the time in the summer. Once, during a family reunion, I stepped outside (after applying mosquito repellent) to join the rest of my family (none of whom had a drop of repellent on them) who had been outside for hours and had to go back inside within the first 2 or 3 minutes because of the 6 mosquito bites I had! And later when they all came back inside, still none of them had any bites! My mom always jokes that when I’m around, she never needs any sort repellent.

    Buggy, May 26, 2010 at 9:57 pm
  113. Blood type O,husband A,live next door to grandchildren type A. Always tought blood types might have a correlation to bites but it is confusing to say the least. I believe maybe like the guy that worked for the conservation district and had built up an immunity? They land on me big time while I’m out spraying them but the bites don’t swell up. My grandkids get bit up so bad ( they’re little,soft skin and no immunity yet? A child of mine when he was about a year old was bit up while he was asleep and he looked horrible. Now hes 18 and is out working in the fields doing farm work and they don’t really bother him as much. I’d like to find out more research on people in mosquito infested countries and yes, why can’t this be pinned down more. Theres alot of mosquitos and alot of people. Wheres the real answers?

    Sageland, May 28, 2010 at 1:02 pm
  114. My husband, blood type A+ body temp runs hot, you can warm cold hands just by holding them near him. He NEVER gets bitten.
    I am type A- average body temp 97.2. I manage to attract every mosquito in a 5 mile radius and each one of them thinks its Thanksgiving and I am the full feast from turkey to pumpkin pie. I get fewer bites when I use repellant, but still more than others around me.
    Neither of us use alcohol at all nor are either of us pregnant. So, either there are holes in this theory or we are the exceptions that make it a rule.

    peg, May 30, 2010 at 1:44 pm
  115. I’m B- and mosquitos attack me every chance they get… my husband, sitting right beside me is never bitten! I’ve always wondered why they liked me soooooooo much! My bites swell up about 4 inches across and sometimes leave a brown bruise-ish looking mark before disapearing.

    suzzi, June 2, 2010 at 8:04 pm
  116. I dont know my blood type but like everytime I come and visit my family in mexico around the summer time, I get bitten like 6, sometimes even more like when I woke up today I had a total about 10 bite marks around my legs and arms and I think I have like two more and everyone else doesnt get bite marks but me. Also do you think its true that washing your body with water and sand from the beach makes them non-ichi and helps get rid of the bug bites?

    Bryan, June 5, 2010 at 6:37 pm
  117. This article is wrong. I’m o+, and when I’m drunk not one bite, while all my friends are eaten alive. But when I’m sober its like the 6 doller buffet outside of a curves.

    joseph, June 21, 2010 at 1:57 am
  118. I think that the temperature theory might be right. When I was younger I used to have the same body temperature as most people (99,5 F). I constantly got bitten almost every day and to make matters worse I was allergic to mosquitoes. I could count to over 30-40 bites most days and they were all very big, red and itchy.
    A few years ago, though, I got hypothyreosis and since then my body temperature is a bit on the low side (96,8 F) and I still get bitten but not nearly as much. Only two bites this year and it seems like I’m not as allergic to mosquitoes as I was before, either.
    I don’t think it matters, but my blood type is AB-.

    Madeleine, June 22, 2010 at 7:49 am
  119. Thanks so much for posting this artcicle. I probably have been bitten by 40, 000 mosquitoes by the end of the summer. It’s insane and at the moment I do not know my blood type but I would like to find out to see if that’s the reason. My friend’s mom told me that Mosquitoes are attracted to “healthier blood” and it makes sense but didn’t know how. SO I researched to see if there were any prooven factors as to why this ALWAYS happens to me. SO the CO2 levels seem like a definetly accurate idea, being the more active the more co2 and in the summer’s that’s me esspecially. SO thanks again for your article.

    Meg Johnson, June 27, 2010 at 10:00 am
  120. So interesting! I’m O negative and mosquitoes don’t bother me but eat my spouse alive if they’re around; but one child is O negative also and seems to get bitten as much as most people. I’ve always assumed mosquitoes like them because they both are much warmer than I am– I tend to be so cold (low blood pressure) while they are both like furnaces.

    Wu Ming, June 28, 2010 at 5:22 pm
  121. Buy a small bottle of citronella. dab a little on shoe or sandle near ankles and perhaps on something like hairband, ribben or something. It has realy made a difference to not getting bitten so much. I always carry a little bottle around to add to tea lights and the smell is not bad either. Clarityn tablets help with reaction

    Michelle, July 2, 2010 at 1:37 am
  122. OK, after reading all this I have it figured out.

    Blood type is not as important as the HEAT you give off.

    I used to never get bit with 0 negative blood, but I never used to sweat that much either, very rarely…that is until MENOPAUSE.

    My husband does not have O, but he sweats, or used to, rolling down his head after 10 minutes out side….and I could not take him anywhere in the heat without him getting eaten alive.

    Now the tables are turned, its me they prefer, because I am hot all the time and sweat easily.

    Lori Muir, July 6, 2010 at 10:41 am
  123. I am interested in the ethnicity of the people who get bites and who do not get a single bite along with your bloody type and weight, height, and gender.

    James, July 6, 2010 at 1:42 pm
  124. I am type O neg and very, very rarely get bitten. My parter (who does not know her blood type) is constantly getting bitten. So much for the O factor. We could be standing side by side and they just love attacking her.

    Terrie, July 10, 2010 at 8:11 am
  125. I am rhesus negative blood type and have never been bitten in my life even though I’ve lived all over Africa – the mosquitoes just avoid me.

    Tracey, July 12, 2010 at 4:20 pm
  126. I have read almost all these comments and have to agree with the amount of heat a body puts off and as I am sure there are other triggers to mosquitos. I usually have 80+ on each leg (from calf to toe) I can wear heavy canvas pants, socks and shoes (they won’t bite through the shoes)they will bite through everything I wear… I have them in my hair, face, in between my fingers and toes, and even on my bumm. I joke that I am meth for mosquitos. I have used every type of spray, cream, oil and lotion …. I have taken B vitamins and garlic…..with no relief at all. I have even used the bug spray that we use on the horses and cows…. it helps alittle but they will bite me through that as well. (Please don’t do it… it is toxic!) The only thing that brings relief from the bites is salt water and sunshine. To those who live near the sea Praise God! go take a dip and soak up some sunshine. To those of us land locked break out the mineral salts and run a bath. I make it a very strong solution and if they are really bad will rub the salt directly on the legs and arms and let it sit for a few minutes. Yeah it burns like heck…but it does seem to relieve some of the irritation. I then rub a combination of Hydrocortizone (strongest you can find… ask Dr.) and Triple Antibiotic Ointment. This does heal the welts and broken skin faster. If someone is keeping an eye on the stats of these posts… I am O-, fair skinned, and have a warmer than average body temp, I also tend to sweat easy. We live near a river and have swarms of mosquitos. I will be checking back to see if anone has more suggestions ……

  127. I am o+ and have never been bitten, my grandfather had malaria from the 2nd world war and my doctor at the time after taking anti malaria tablets said that i could have some kind of antiboby

  128. Had to post this as i worked out in san tome in 2000 and me and my mate sat outside a bar and he watched the little bastards land on my legs for a few moments and just fly away, do a lap of the bar, land on him and start sucking!!!!

    Richard 1972, July 22, 2010 at 4:27 pm
  129. Interestingly it seems that people who get bitten have chosen mates (partners) who do not?? Maybe there are pheromones that we select for, even in this case! I by the way, do not get bitten- they hover over me- rarely land (The only type of mosquito to feast on me was in japan it has White striped legs) growing up I was bitten and had terrible swollen painful bites. My husband, for the record, gets eaten alive by everything!!

  130. this is quite interesting, even for me who does not know wht her blood type really is ((supposedly an o))… I get bitten every summer, and sometimes it just itches and the other it doesnt at a certain time of day in the summer… be it the afternoon to 3pm, when its really hot, the fan is on, drinking something super cold like the usual ((even in winter too… i just dont know y i dislike drinking something hot or warm…)) THIS IS JUST WHERE IT STARTS… when my skin becomes sweaty and hot, they come eating me alive… when my skin gets goosebumps or dehydrated or cold ((yes, in the coldest room available where they shouldnt reach at all)) i dont feel like they bit me at all and most often it doesnt itch at all at first….. O.o
    And it also sucks to be the target… -_-;; I live in a family of 6 ((me, older brother, parents and grandparents))… everytime theres a mosquito in the house, they come looking for me instead of the others… my parents get bitten seldom… the others none “just cuz theyre mostly around cigarettes”!?!? You see, i hear tht bugs including these dislike smoke and tends to get away… btw, i never saw my bro get bitten, but if he sees one he wouldve smacked it dead ((in all possible corners and places, except cobwebs))…
    Just to say wht i think, i think tht ppl who are o- and o+ are like just opposite preferences for a bloodsucking mosquitio… even if u are an o and u dont kno whether ur + or -, might as well think how mosquitoes get to ur place first and then onto u… for me, w/o a doubt its the front and back door thts open at a certain time for a certain amount of time……… UGH….
    Anyways, thank you for posting something interesting, peeps~ =D

  131. For most of my life I was bitten occasionally but not a lot, despite having an outside job in the woods. My body temperature ran about a degree below average normal (97.6 instead o 98.6). A couple of years ago, I learned that I had hypothyroidism, one or the symptoms of which is low body temperature. I am now taking 95mg per day of porcine thyroid extract. This summer I have been bitten dozens of times in a single day. I also have received most of my bites where the skin is thinnest (forearms, side of neck, etc.). Maybe body temperature really is one of the things that attract biting insects. I think I’ll start eating garlic and see if that helps.

    Tom, August 22, 2010 at 11:01 am
  132. My wife, daughter and myself (Californians) went vacation to Bremerton,WA a week ago and noticed that 3 of us got bitten but not the people we visited. Perhaps, these bugs like new blood? It is like new dishes on the dining table haha.

  133. Hey there Gang, I’m O negative, I’m always’s HOT like a furnace, don’t like the heat or sun. I know my skin temperature is warmer than other’s. Cause they where jacket’s, and I’m still in my T-shirt. But i don’t sweat as much as other people, when other people do. I am Caucasian but i hardly ever drink at all, maybe twice a month. Ok(Listen)i get bit up so dang much, every little insect. Mosquito, Fly, Flea, Spider, Asian beetle, Leech, Centipede, Chigger’s, Louse, Scabies, Crab’s, Wood tick, Etc. I can come in from one night at a camp fire, with my body doused in bug spray! My friend’s might have 2 bite’s. I will keep getting outbreak’s for 5 day’s!!!! 30 bite’s on my leg’s, neck, and arm’s, mostly by the elbow’s! So i just don’t go outside no more at dusk. (8:00-10:30) One weird occasion~ my Son and i living together, Same blood line! Had an outbreak of cat flea’s, had to bomb the house. I got bit over 100 time’s. How many for him, a couple? So some thing’s that might be different from what people are saying here? I Love to eat a lot, Mushroom’s, Onion’s, Bread, Milk. But only my gut is obese, my arm’s and Leg’s are normal where they like to bite. Have sweet underarm deodorant, sit still (relax), and i can feel every tiny thing on my skin. But hey one thing i know for a fact. I was cooking hamburgers in a cabin, out in the deep wood’s. The smoke was only going out one window. The screen was loaded with over 600 Mosquito’s, but absolutely zero on all 3 other window screen’s. They can smell the blood from the burger!!!!!!!! So may~bey they bite me so much more, cause my blood is closer to the outer layer of skin? And if they can smell my food closer to the surface also? I have also tried Garlic.

    Crazy, August 25, 2010 at 11:19 pm
  134. I am type O Negative and I do NOT get bit. I also have the blood disorder ITP that someone mentioned above and they said they get bit all the time, well again I have that and do NOT get bit…..You know what makes sense?? Some of us have a gene that causes us to give off certain chemicals that repel mosquitoes and some of us don’t have that gene. It’s natural selection. As in how some people carry genes that kills the malaria virus and some don’t. This is needed in some areas, like parts of Africa, for the people to even survive OR malaria would wipe them out. Same thing goes for the Black Plague; a third of the population was killed, but the survivors carried a gene, I think it’s called Delta 32, that destroyed the sickness; without that gene everyone would have died. Therefore, mosquitoes carry diseases which are a threat to humans, if everyone in the world couldn’t repel mosquitoes in some way, if everyone in the world didn’t carry a gene for it that they could pass to their young for generations and generations of human survival…then some parts of the world, or maybe all parts of the world, wouldn’t be able to survive. It just is what it is people, you may not carry the gene to repel mosquitoes, but you might carry the gene that kills aids, or malaria, or whatever else.

  135. My husband and I are both “O” blood types yet I am a mosquito magnet and he is not. I am so frustrated whenever we travel I end up with welts all over my body and he has none. I realize there must be something different in our chemical makeups otherwise it just doesn’t make any sense. Just yesterday, we were in a situation where there were a few mosquitos and I can count today, I have 9 bits and he has 0. I must admit, I do not use insect sprays on my body, which I have to start doing. It’s an awlful thought that every time I go outside I have to lather up with insect replent. There has to be an alternative.

    azallie, September 5, 2010 at 10:28 am
  136. I don’t know how they concluded that study. I’m type O and I rarely get bitten while my boyfriend is type B and he always gets bitten.

    Megan, September 6, 2010 at 9:26 am
  137. I’m a type AB(+) and I get bitten every time if it happens that I’m late outside and in their presence. It’s pestering that they’ll always come for me in the midst of other people. It’s one thing am eager to know why, not found satisfactory reason.

    Werason, September 12, 2010 at 6:33 am
  138. I have B- blood, i drink everyday after work, and i’ve been out and a bout in areas so clogged with mosquittos that i’ve got landed on many a time, but not a single bite. i got bites as a kid, but it decreased when i hit puberty at 17 or so, and at 25 or 26 i haven’t had a bite since, oh and i also don’t like sweets much, they build up for me like when you eat something spicy, the same thing happens for sweets with me, so there really isn’t a point in getting a candy bar/slice of cake if your only having a bite…

    so hence my question?…


    Jonathan, October 1, 2010 at 11:37 pm
  139. hello everyone. i have always been biten by these pesty blood suckers. and i to get attacked before i even get the door closed good. i hate it . i love outside. i am O+ body temp runs 97.3 i am female, whilte and 47. it does seem the bite have increased the older i have gotten. a friend told me my cholestoral must be high the bugs love the stuff. anyone heard anything bout this being a possible cause. by boyfriend takes cholestoral lowering drugs and never get bit. just a thought.. maybe we should all have ours checked.

    karen, October 3, 2010 at 2:25 pm
  140. on holiday recently in goa we stayed with some friend who have lots of land whith cabins and a huge lake 20 yds away , having slept under the mosquito net all night i needed to go to outside bathroom at about 6-30 am yes thats right dawn during my short stay i looked down onto my cream trousers and counted close to 20 mozzis per leg . where were the rest i thought . oh my they were everywhere and i mean everywhere. they say that the mosquito will go for the thin skin on the foot,but i was wearing slippers the next area is the hands and then the privates yes the groin,10 -20 bites lots of blood there. lesson to be learnt bathroom only when the sun is high in the sky. happy holidays

    patrick, October 3, 2010 at 4:52 pm
  141. I am O+ and I am constantly getting bit by mosquitoes.

    Lisa, October 3, 2010 at 9:24 pm
  142. I am 35 and O – and I am currently covered in bites, which increase in number every day because of where I live and work. I manage a hotel that is surrounded by bush over looking a Lake and now that it is spring I wake up with more everyday very fustrating because they swell up and ache, I even remember going camping when I was young and counting over 100 bites on my arms. It drives me crazy, today I have been googling how to ellimante these bites no one elses seems to get biten if I am around. My partner went out this evening at dusk and had they landing on him and not one bite …..

    Teresa, October 6, 2010 at 7:05 am
  143. my friend and i live in one room.my friend is not bitten by mosquitoes and bed bugs.when a mosquito bite him it is killed by itself.i asked him why mosquito does not bite him?he replied that every year in spring season ,he drinks the decoction of indian herb [chariata] for 1 or 2 days.and so he is never bitten by bed bugs and mosquitos

    omoron, October 6, 2010 at 9:53 pm
  144. i have sensitive skin. i easily get allergic reactions from mosquitos… i got mosquito bites most of the time. =( … and im currently living under tropical location, a breeding ground for mosquitoes.. i hope there are other ways to prevent being bitten, other than DEET lotions..

    i think maybe, these ways the mosquitoes pick their victims, as i observed.. they are the following:

    d.) glucose factor – maybe they tend to look for targets whose blood rich in glucose content, coz glucose is energy. thus making them alive and filled with energy. glucose can easily release energy providing heat. blood + glucose

    b) person who sweats / or “on heat” – if the person usually sweats, that means the body is on heat, thus making the person an easy target. if heat is detected, that means blood is fresh, and thermal. if they get cold blood, it would not be easy for them coz the blood is going to coagulate.

    c) CO2, h20 and oxygen – most mosquitoes dwell in plants(like tropical areas) and stagnant water. may prove significant.. they do need water, just like living plants and animals do.

    d) skin type – after they found a prey, they determine the skin type, usually sensitive skin, or pale skin, and thin skins. so that it would be easier for them to bite. if skin is thin, they can easily attack without trying too hard with their teeth.

    e) people who wear dark colors – maybe they have eye sensors/multi sensors that can detect heat through dark backgrounds.. if someone wears white/light clothes or in lighted areas, their ability to detect preys can be frustrating

    i’m not sure about this, but maybe.. as pointed in the previous posts, (thanks to you) above and recent searches i did over the internet. i could be wrong. ;)

    i might as well try to take chariata as posted above in a week and see what happens, it might help. i searched about chariata, and it says it lowers down glucose.. this might solve our problems! :)

    kris, October 17, 2010 at 6:18 am
  145. I’m O+ & male & I’m constantly bitten by mozzies. My mum & sister having A blood-type are not bitten despite walking with me through the forested area. I’m wearing light-coloured shirt so that rules out the reason why I’m bitten.
    Could it be a combination of blood-type O+ & being male with male pheromones that make me a magnet for mosquitoes? After all, only female mosquitoes bite.

    mozziekiller, October 21, 2010 at 5:28 am
  146. A- blood. fair skinned -tried high protein diet and then veggie diet,Didnt work. EATEN ALIVE by all insects. I am now battling ticks who bite me with gusto and my son gets no bites . I am now getting bitten by TICKS INSIDE the house. He has no bites.Im SURE it is a chemistry problem. But why on earth doesnt someone figure this out? They could make a fortune. I am going to try the chariata. Dont even know what it is but who knows when your lucky number will come up? Enjoyed the comments. At least I have some company with this terrible malady. Modern science or drug manufacturers should see some money in this? But maybe not enough.Lord have mercy on us all

    Patsy McLamb, October 26, 2010 at 2:12 am
  147. I am a blood type AB+ and i still get bit very much from mosquitoes, i think it doesn’t matter which blood type you have. but hey everyone has there own theory and beliefs.

    Victor Ochoa, October 30, 2010 at 2:23 pm
  148. BECAUSE MOSQUITOES DONT BITE APES, Oh, yes….. this is the subject of evolution. Many published studies over recent years have shown that chimpanzees mostly have Blood type A, almost no Blood type O, but never Blood type B. The other great ape, the gorilla has Blood type B, almost no Blood type O, but never Blood type A. In these ‘man-apes’ species, said to be the ancestors of man, there is NO Blood type AB in either. Generally speaking, man has both Blood types A and B, and Blood type AB. Blood type O, in man is by far the most common in virtually every racial group.

    MALCOM ALEX, November 12, 2010 at 8:47 pm
  149. i dont kno my blood type i never got bitten by mosqitos

    blobie, November 18, 2010 at 1:39 am
  150. I get bitten by mosquitos all the time when im in the same room as my brother who does not, even with repellent.

    Snoop dowgy dowg, November 24, 2010 at 8:16 am
  151. Thank you soo much for the informations. Now I understand why i get bitten soo much everyday i will get few here and there. I get soo frustrated over it and decided to looked up on internet. Well i am not only Type O blood i am also Pregnant this is why i get bitten everyday at all times….

    Nanak, December 6, 2010 at 9:40 am
  152. I’m sat online reading this article because I can’t sleep. Staying with family, forgot the repellent and everytime I try sleep, I hear that annoying little whiny buzz in my ear and soon I’m bitten and itching all over. About 20 bites so far this evening and not a minute of sleep. Doesn’t matter what I wear, I can even lie completely covered in my sheets and they just bite through. If I use any kind of skin repellant, they just find the spot I missed and I end up with bitten lips, ears and eyelids. I live in South Africa, Spring through to Autumn me and my two sons get eaten alive and guess what? My husband gets none or very few. My husband has a much warmer body temp than me, my kids average. Blood groups all different. Not pregnant, vegetarian but my sons and husband eat meat. Sadly, having sat here and read this article and comments through, I’m none the wiser and I really wish I’d found a cure!! Although it did distract me from my bites for a short while.
    The only factual observations I can make after 40 years of being mosquito chow;
    1. My kids and I get bitten at night most, while we sleep or try to sleep, and the ONLY thing that can prevent it is a plug in mossie killer plugged in a good hour or so before we go to bed. Keep windows closed. There’s nothing that will stop us getting bitten outside in the evenings or early morning so we just avoid it at all costs.
    2. Different types of mossie can cause more problems; we’ve found one type with black & white legs is particularly vicious? Anyone know why?
    I wish somebody could figure it out, any more diet info – love to know if garlic works. Hey, f@*k it, love to know if ANYTHING works.

    Weeza, December 25, 2010 at 10:21 pm
  153. How frustrating! Over three years, 152 comments, and only one article addressing the reasons some people are magnets for blood sucking insects. mosquitos, no-see-ums, certain flies, and the Red Cross– they all like my blood. As a universal giver I don’t mind giving to the Red Cross. I don’t even want to see the demise of the insects. I just want to prevent being bitten. There must be a scientist in a lab somewhere that is interested in making a lot of money. I would be like a kid on vacation and spend every dime in my pocket for relief from irritating and oozing bites. In the meantime, I am going to try the garlic treatment since none of the scientific studies up to 2007 seem to have any answers.

    Michal, January 5, 2011 at 11:09 am
  154. So I’m A positive blood type and mosquitos, fleas and grass bugs love biting me! Its sooooo annoying to say the least, I went to the park to walk my dog I was wearin jeans a sweater tennis shoes and they still found a way to bite me on my arms and thighs and hands its ridiculous they need to find the real reason and solution stat! : ( until then they continue to feast on me!

    stephanie, January 23, 2011 at 12:25 pm
  155. If you are the type who react strongly to insect bites – site becomes red and swells, feeling hot and itching or even burning, homeopathic remedy, Apis 30c can help. To reduce the symptoms take every 1/2 hour till the itching subsides max 5 times. Ledum 30C can also help with bites that itch but aren’t swollen and red. Apis and Ledum antidote each other as I discovered when I took first apis for a bee sting and then ledum the next day for an ant bite – the site of the sting started to itch and burn. I repeated the apis and sting was better. Caladium 12c is a remedy that can make a person unattractive to mosquitoes, but also makes cigarettes taste horrible. I recommended it to my son’s horse riding teacher as she is always being bitten and she told me she started to dislike cigarettes, when I looked in the materia medica it was also noted there the dislike of cigarettes. Hope this helps some people.

  156. wow i didn’t know that, p.s i am really in school im just a bit smart….

    Emma, April 7, 2011 at 9:40 am
  157. I realize this thread is really old, but have any of you tried Cutter’s bug repellant? I get eaten alive if I don’t use it, but am totally protected if I do. OFF is a joke, as well as Skin So Soft. And my blood type is O+.

    Karen, April 11, 2011 at 3:29 pm
  158. I am agreed to the theory and with Allsion. And i also appreciate Angela to give a good solution by using the homeopathic medicines and cure yourself from mosquitoes biting as well as get rid of nicotine.

    Iftekhar, April 15, 2011 at 11:56 pm
  159. I have recently moved to Dubai and I seem to get bitten all the time from mosquito’s and take a bad reaction to them my foot is really swollen and itchy so annoying.
    Its funny as my husband dont seem to get bitten nor does my youngest son, it only seems to be myself and my oldest son….. now a may be wrong but me and my son both have red hair could that have anything to do with it plus I am A+ blood type. why o why o why do I keep getting bitten????

    Alanah, April 19, 2011 at 2:20 am
  160. I just found out that not only is type O a hot commodity for mosquitos but also the darker color of what you wear and skin tone attract mosquitos. That why when you see a gardner wearing a lighter color its not to help the plants (i don’t think) but to keep away those pesky blood suckers…

    Becky, April 20, 2011 at 2:04 pm
  161. It’s funny but seems like the medications I’m on seem to have a lot to do with it…when my doctor upped my divalproex they didn’t bite me quite so much anymore. But then when he switched it to xr they showed some renewed interest…same with the seroquel. Now I don’t call myself an expert or anything but I do so hate anecdotal evidence and how suddenly everyone’s an expert right…well when I went off my fanapt, i started getting bitten all the time and especially at night! After a few days…well the mosquitoes became bigger…I asked them once but as it turns out they only speak russian.

    Brunhilde, April 26, 2011 at 5:03 pm
  162. My dad has always been bit by fleas &Mosquitos (he is O positive) I have been blessed with the same attractivness with these vampires ( I am A positive a given because my mom is A positive) and these blood suckers dine on me as much or more than my dad. I think that fleas are the worst as they are more insidious and let’s face it there is more shame when you share with others that fleas dine on you! My legs bear many scars from previous attacks & am well aware that I should not scratch but I cannot help what I do in my crazed sleep state at night! My reactions to flea bites look more like what one would think a spider bite might be and if I dare to scratch, I get a huge ugly bruse around the bite area- not attractive for a ladys leggs! I just returned from Florida with a group of professionals and I was the only one that I know of that was tormented by “sand fleas” it looks like I have a disease especially if I’ve scratched and pus is on the bite. One year along time ago (before treatments for animals came out like Frontline, I was so tormented by this that when I happened to nail a flea that jumped on me I would grab it between my thumb And finger and drown it in “Compound W” just to make it suffer, I was at my limit!!

    Patricia, May 3, 2011 at 1:20 am
  163. Im O- and I get bitten alot more than my family of different blood types

    lisa, May 17, 2011 at 2:00 pm
  164. My body tempature is 96.8 and i never get bit and my carbon dioxide is low my grand mother was the sam way she lived on an house boat in the Atchafalaya Basin

    seascoutship9, May 22, 2011 at 8:16 pm
  165. same

    seascoutship9, May 22, 2011 at 8:16 pm
  166. I am from Tanzania East Africa and i have been bitten by mosquito even during the daytime.It was so hard for me to explain but now according to this post i got some clues on why mosquito prefer by blood compared to other people.The explanation is interesting but further investigation should be done and if possible to isolate genes from individuals who are malaria resistant and transfer to our susceptible bodies.I am sure science can do this what we only need is enough information and the mechanism behind.

    Esso, May 24, 2011 at 1:13 pm
  167. Im type O+and in one day I get as many as 15 if not more bites per day..my husband is ab and he can stand right next to me and never get bitten…look forward to this summer being pregnant and with a temperature..

    Luisa, May 31, 2011 at 4:23 pm
  168. I spent 2 weeks in Dakar Senegal and didn’t get bit by one mosquito but they love me in Connecticut USA. I have B+ blood. My husband gets bit but they don’t itch. I hate him for that!

    Carrie, May 31, 2011 at 9:29 pm
  169. I knew it was the alchohol, party and me being there mobile kegger..lol . I get tore up way worse than everyone around me, it sucks even with a way lot of bug spray..kind of wondered if surgeries that you are given someone elses blood could make a difference also?

    mike mccormick, June 2, 2011 at 8:46 pm
  170. thanx 4 the article ahh they really hurts

    PRASHANT CHAUHAN, June 3, 2011 at 9:10 am
  171. My family and I went camping last summer near a lake. All the memembers of my family got a few mosquito bites here and there, maybe four at most. Except for me. I got 47 bites total. I counted. They were all over my arms and legs, and I looked like I had the plague. Luckily I don’t live in an area that has mosquitos but when we go on vacation somewhere that does this ALWAYS happens.

    alyssa, June 5, 2011 at 12:01 am
  172. I used to live in Thailand/Cambodia a few years back and the locals told me to stop eating banana’s as they have some chemical that leaches from your skin and is an attractant to those pesky little creatures.

    Juniormark, June 11, 2011 at 2:23 pm
  173. Several years ago I did a report in college concerning DDT. From what I found out, DDT is safe for humans and nature but it was a dispute between two competing insecticide companies. While in the AF they would issue us small cans of it to spray inside our aircraft prior to landing and give us spray cans to use in our rooms when we went to Southeast Asia. When DDT was legal, Malaria was practicly wiped out. There were less than 5,000 cases a year through-out the world. A few years later and today, there are over 60,000 cases a year. Please don’t beleive all the hype you read about it. Though nothing is totally safe, it is much safer than Sevin or other stuff thats still in use. We need to bring it back. Do any of you remember when they would drive around fogging the neighborhood? I was a kid back then and I do and that was DDT and I never heard of anyone developing some wierd disease or birth defects and we would have fun running THROUGH the fog….If you’re worried about the diseases mosquito’s carry, then you should write your congress person and have then re-evaluate it and then legalize it for household use.

    Peskybynature, June 11, 2011 at 2:34 pm
  174. This is indeed a weird phenomenon! My husband and I both have type O blood. I rarely get bitten but he does! Once on vacation we went for a romantic stroll and he came back just covered with mosquito bites, but I had perhaps one. Same thing with my last boyfriend, I’m not sure what his blood type was, but he was a big drinker. Any time there were mosquitos in the area he’d get bitten, but not me!

    V_T, June 13, 2011 at 3:36 pm
  175. I have high iron levels (beyond high in fact) and I have Factor V Leiden (which is a blood clotting disorder). These issues are genetic and I am positive that I get eaten alive every year (as does my Mom) because of our blood disorders…………I am A+. Last summer I sat out one evening with my dad and I got 50 bites in a couple hours and he had NONE!!!! I think they like my thicker blood that is very iron rich. These are both problems for me but they may be seen as appetizing to mosquitos sadly. We all know that iron in the blood has a distinct smell and I think that mosquitos can smell that which makes me a target. I’d be curious to know if other people with either high iron levels or clotting disorders have major problems with mosquito bites! Also, one woman wrote above that her bites are unbearably itchy and end up looking like bee stings – I hear ya!!!!!!! So for me (and my Mom) it;s not just about the frequency of the botes it’s also about the intensity.

    kmoore, June 15, 2011 at 11:53 pm
  176. I have 6 brothers and sisters and NONE of them get eaten up as much as me. Can anyone explain this?!?

    M_P, June 20, 2011 at 6:12 pm
  177. i battle mosquitoes every single day…they follow me and if i am in pajamas or dress socks with a thin layer of fabric over my skin some how i get bitten…so then ive been told that its what my body gives off…i take a shower come back not even one minute i get bitten…unless im moving they wont bite…im not obese or fat at all but rather at a healthy weight, nor do i breath heavy(how do you know? well i breath through my nose Not my mouth even when i sleep because ive told my brother to tell me because he has seen me sleep), but i am the type that wont move while sleeping or standing and also i am a “warm” person meaning i like the cold a lot…where ever i may be they love me no one else out of the other 5 people here living…

    AC, June 22, 2011 at 8:37 am
  178. I have Blood type A-,so that blows blood type out of the water-because no-one has mentioned blood type A-.My husband is type O+ and he does get bitten but not enough to makes sense of the O blood type theory. So I don’t think its blood type at all. I do have asthma and allergies so that one is a possibility. I do believe in the predator effect because in the sun they don’t seem to be as bad. No matter what I get eaten alive and then the bite swells to a whelp the size of a fifty cent piece and then turns to a bruise that lasts for weeks as far as the itching Bennedryl gel stops the swelling and itching after a few applications.. Mosquito repellent really doesn’t help prevent the bites. I am more likely to agree with the theory of maybe emittions of a favourable feast smell from certain people. Once they isolate that pheromone they will have a solution to why mosquitoes bite or annihilate certain people.

    Tess, June 23, 2011 at 9:50 pm
  179. I am 0+ and i got 4-5 bites in my life.And i am 18. WHY I DON”T GET BITTEN!!!!
    It’s not that i want but this blood tyupes theory is wrong.

    Smilor, June 27, 2011 at 12:19 pm
  180. And… that picture is wrong… Haven’t seen mosquito like that one in years!!!
    These are new… they are black and have white lines on their legs and body.

    Smilor, June 27, 2011 at 12:21 pm
  181. Diet: high calorie, plenty of white meat (almost never red) and sugar
    Metabolism: very high
    Blood type: O+
    Exercise: 7 hours+ cardio a week / 4 hours+ weight lifting
    Skin: fair
    Smoke/drink: pack a day, six pack at least once a week
    Stature: 5’10, 165 pounds, medium frame.
    Caucasian of German descent.

    Now, here’s the thing. The above descriptions fit both my father and I. The biggest difference between our physical appearance and anything listed above is that the veins in my arms are much more visible. He almost never gets bit. I get bit very often. Here’s the kicker: only one of every thirty or so bites ISN’T on my arms.

    Also, last week after a more-intense-than-usual leg workout, my veins were showing a lot more than usual and, go figure, once I went outside they were comin’ straight for my legs.

    Dave, June 28, 2011 at 1:54 pm
  182. I have a theory: DIET.
    Doesn’t that make sense? The blood will have different levels of nutrients, and therefore will smell different to mosquitoes. And apparently drinking Apple Cider Vinegar will help deter these nasty ol’ buggers.
    Just a 16 year old’s input. :)

    Christie, June 28, 2011 at 5:28 pm
  183. I am type O and over 40 and I don’t remember when the last time I was bitten even when I was in an area that was infested with thousand of them. I guess I am lucky!

    Cheri, June 29, 2011 at 5:15 pm
  184. Every single night I put on about 3 soild layers of deep wood off before I go to sleep. Also put on the ac and put on a blanket. And in the night{This is a sleeping disorder put i am treated} I put on another 3 layers. The first time I put the off on and then wake up to put more I see some on my leg near my ankle. I thought it was bed bugs, but it was not. {I did not know it was mosquite until moring.} So after wakeing up with 3 other three layers I saw more and I did the exact some thing i DID AT FIRST. wHY IS THIS Happening to me?????

    Niki, June 29, 2011 at 9:37 pm
  185. i can watch them land on me all day, pet them and they fly away without a bite. now my guy friend who is type 0 not only gets bit, but also gets these God awful, large red areas of the bite site. i feel badly now for laughing at it at first because i’ve never seen anything like that from a mosquito bite. he has a doctors appointment tomorrow…..

    mojo, July 5, 2011 at 8:22 pm
  186. Im type 0+, and i get bitten all the time; when nobody else does. High body temp too , so this makes sense for me.

    tashia, July 6, 2011 at 9:28 pm
  187. Hi, mosquitoes bite me and my children a lot than others. Do you have any suggestion about this. Thanks.

    mosquito killer, July 7, 2011 at 4:39 am
  188. Only twice in my life have I met someone who gets bitten more than I do. I sheepishly admit that I enjoyed the outdoors much more when I was around these people! I could sit and relax, unmolested, while the other poor sod slapped and twitched and scratched.

    And it’s not just mosquitoes that I attract. Deer flies horse flies, black flies, fleas, bedbugs and no-see-ums all prefer me. Bites raise up higher and take longer to abate. I came home from 3 months in Africa joking that “even the butterflies bite.” Once I have accumulated 5 or 6 bites I am so itchy all over I can’t even locate the actual bites.

    I don’t know what blood type I am, but even as a child I was always too hot and sweated readily. My skin is acidic. Would that mean I exude the lactic acid some studies are looking at? It seems to make no difference if I have bathed or not, eaten bananas or not, am wearing dark clothing or not.

    I know bats, swallows, frogs, and dragon flies need to eat…..but the world would be a better place without these tiny, whiny killjoys.

    Elly, July 7, 2011 at 3:23 pm
  189. I’m also an O-. I can be sitting at a bbq and everyone is swatting and getting bitten, and I never get one bite…. My husband is A- and never gets bitten either. After reading everyone’s comments it seems you are less likely to be bitten if you are an O.

    Brenda, July 8, 2011 at 5:32 pm
  190. I have been known to get as many as 30 mosquito bites in one night. I was outside with my friends for the 4th and got 10 bites. I was sitting in the smoke of a bonfire and no one else walked away witha single bite. I am O+.

    Katie, July 8, 2011 at 9:25 pm
  191. I completely disagree with the blood type theory. My father and I both have A+ blood. I had just recently come home from a family vacation in the caribbean; I have over 160 bug bites on my legs and arms while my father only has 2 bites.

    Danielle, July 18, 2011 at 12:45 am
  192. Thank you. That was useful. Im blood type AB and I get at least 4 mosquito bites per day. If I lived on a farm, I would get eaten by mosquitoes. (Its a good thing I don’t live on a farm :))

    Jerome, July 21, 2011 at 7:34 pm
  193. Acctually, im AB+.

    Jerome, July 21, 2011 at 7:43 pm
  194. I am type A- and get bit alot and get huge red welts. Washing with soap and water and then applying caladryl clear seems to be the only thing that takes away the initial burn and itching. My husband is O+ and hardly ever gets bitten. My father also was a mosquito magnet getting big welts. I hate using repellent since it seems to cause acne breakouts. (the undergrounders that just hurt and are watery) I don’t know which is worse. Sheesh. I love summer but hate those little buggers.

    Audie, July 22, 2011 at 1:14 am
  195. Why would anyone trust an article on mosquitoes that mistakenly used a picture of a freaking CRANE FLY as the image?????? They are probably wrong about everything else!!

    Jonas, July 22, 2011 at 10:34 am
  196. For Mike at #5, I knew that yours would be one of the lamest comments here as soon as you stated about “mosquitoes feed their young.” Dude… take a class.

    Ron, July 22, 2011 at 2:44 pm
  197. B+. I get hammered daily here in Colorado. Same as a kid and young adult living in humid East Texas. Surely science and the pharmaceuticals can join hands and produce something that we can consume that will then be a part of our blood-markers and not only deter the mosquitos but mortally impact them. But then what would we do with all those insect repellents and deterrents that we spend a fortune on and enjoy spraying ourselves with (surely over time this will harm our atmosphere and our lungs???)?

    Mark, July 24, 2011 at 12:44 am
  198. I have always been eaten alive by the buggers. I used to go thru tons of benedryl spray for the itch. I have found the best solution for the itching. Anti itch ointment which is actually just hydro cortisone. It takes a little while to stop the itching but I usually only have to apply once.

    beth fitzgerald, July 28, 2011 at 7:26 am
  199. I am blood tyoe AB, and always get bitten. Blood typeAB is supposed to repel mosquitoes. WHY DO THEY BITE ME THEN?!?!?!

    Judith, July 30, 2011 at 11:30 am
  200. These idiots that are denouncing the blood type theory because they are an O blood type and never get bitten, PLEASE REREAD THE ARTICLE AS IT STATES YOU ALSO HAVE TO HAVE THE GENE FOR THE MARKERS, and if you don’t (which obviously you don’t) then that would explain why you don’t get bitten. Please don’t try to make points if you can’t even understand the article to begin with. Ugh.

    Priscilla, July 31, 2011 at 2:05 pm
  201. Hi, not sure what blood type I am but my girlfriend gets bitten to Hel and I have never been bitten EVER, we sleep in the same room, bed, tent what ever, I have just watched a mosquito land on me and furiously try to bite me, then it gave up. Maybe it’s nothing to do with blood type bit skin type as a don’t have any mark what so ever, I guess I’m just lucky, sorry guys.

    Garrick, August 2, 2011 at 1:50 pm
  202. And also wouldn’t the mosquito have to bite you to find out what blood type you were, if you didn’t taste nice wouldn’t you still have a lump from the bite, makes me think it’s about skin type more than smell and blood type as one tried it’s best on me and I didn’t have a mark what so ever. But what do I know, I’m just a plumber.

    Garrick, August 2, 2011 at 2:34 pm
  203. the reason cause of mosquitoes biting us not only related with blood group… please read the article fully again… body temperature, carbon dioxide, blood group o… this is extra information i get from other articles Mosquitoes are attracted to dark colours, not only black, because dark colours absorb heat and lighter colours tend to reflect heat. Since mosquitoes have sophisticated and highly sensitive heat sensors, they tend to be more attracted to victims dressed in darker clothes, where there is more heat.
    Bob, a fisherman, takes one vitamin B-1 tablet a day
    April through October . He said it works. He was right.
    Hasn’t had a mosquito bite in 33 years. Try it.
    Every one he has talked into trying it works on them.
    Vitamin B-1( Thiamin Hydrochloride 100 mg.)

    If you eat bananas,
    the mosquitoes like you, – something about the banana oil
    as your body processes it.
    Stop eating bananas for the summer and the mosquitoes
    will be much less interested.

    This is going to floor you, but one of the best
    insect repellents someone found (who is in the woods
    every day), is Vick’s Vaporub.

    Plant marigolds around the yard, the flowers give off
    a smell that bugs do not like,
    so plant some in that garden also to help ward
    off bugs without using insecticides.

    “Tough guy” Marines who spend a great deal of time
    “camping out” say that the very best mosquito
    repellant you can use is
    Avon Skin-So-Soft bath oil mixed about
    half and half with alcohol.

    LAWA, August 8, 2011 at 5:07 am
  204. Why do I get a heck of a lot more bites than my twin sister, same genes, same blood type O+ ???

    Teresa, August 15, 2011 at 6:29 pm
  205. It only started this year. I had 17 bites one time. I cannot go outside any time of day/night even for 10 minutes and I get a bite. My husband gets none. I am B blood type. After reading this. I do eat a lot of sweets and have been eating more fruits and vegetables. I just started drinking tea with honey in it in May. I believe the honey and or tea might be a factor.

    Annie, August 21, 2011 at 10:22 am
  206. I am B and used to alwasy get bit. I started drinking Vitamin B and I don’t. I just read it hasn’t been proven that vitamin b helps, but every time I do outdoores with mosquito infected places, it does seem to repel them. If I forget, then I seem to attract most, which other humans around actually enjoy. Maybe it is a placebo, but then my idea of being less attractive to them seems to work by itself.

    Alex, August 27, 2011 at 11:32 pm
  207. Try using Listerine mouthwash. Put it in a spray bottle and spray any area that’s exposed.

    howard, August 29, 2011 at 5:53 pm
  208. I do get bitten. I have watched mosquitos and other insects bite me. I am o+ but do not get bitten as often as other people. I also do not react to mosquito bites at all. I am trying to understand the cause. My daughter is 10 months old and gets bitten several times a day. I didn’t really pay attention to mosquitos until now. I have to check the house several times a day to make sure no mosquitos have gotten in. Unfortunately I live near the water and they are out like crazy.

    Anne, August 30, 2011 at 1:28 am
  209. My blood type is O. Mosquitoes love me. I swim laps every night and I wear a bathing cap and goggles and they still hover over me. If I swim back stroke they bite my forehead. I don’t spray anything on my skin and I am mostly a vegetarian. Help . It’s not fun.

    Cecilia, September 3, 2011 at 4:27 pm
  210. My husband is type O, he gives off a lot of heat, sweat smells differently, maybe toxic sweat, perhaps this is what repel insect bites for him. He is Caucasian with sensitive skin and pale. He drinks more than I but perhaps a few beers a week or daily. I hardly drink beer or other alcohol. Neither of us smoke. I’m type B blood of Asian descent. My body temperature is on the cool side. I am very sensitive to insect bites and get bit a lot. Do you think mosquitoes are attracted to the health of a person’s blood?

    autum, September 13, 2011 at 2:14 pm
  211. I dont believe the blood type theory but as far as the body temperature I would agree its partly responsible.Mozzies need protein and iron from you to feed the eggs so if you have more of these in your blood then you are a more favourible choice for food.
    I have a common genetic condition called Hemochromatosis
    that is hereditory and means my liver lacks the enzyme to stop my body absorbing Iron and this makes me a sitting duck everywhere I go

    Trevor, September 13, 2011 at 4:55 pm
  212. i dont know my blood type, but from what i’ve read here i don’t think it’s got anything to do with being bitten. I’m suffering here, in greece, covered in bites, swellings and reactions….i hate mosquitoes …make them extinct…the only positive thing is i now know i’m not alone in this hell…oh and of course i’ve tried everything from the foul deet sprays to citronella, you name it, garlic, b vitamins…plug in equipment…coils…and all at the same time too…i wear socks sprayed in deet and jeans and shoes and STILL get bitten on the ankles! nothing works…i want to find a way to kill them as painfully as possible.

    jim, September 17, 2011 at 6:34 pm
  213. I am type A- & I get eaten ALIVE!!!!!!!!!!!!!! Not sure if the type O theory is certain.

    kris, September 26, 2011 at 6:11 pm
  214. I’m White Caucasian, o+ and seem to be bitten more than most.
    It various with where I am however- in Delhi I bought a local repellant , Odomos, which worked a treat. Avon skin-so-soft and/or Deet worked v well for me in Tanzania and Rwanda, but not in Malaysia and Singapore…

    cp, September 28, 2011 at 10:11 am
  215. Pesky mozzies see me as a mobile buffet! I’ve just had a family holiday in Italy and I was the only one out of 5 of us who got bitten even though I was plastered in repellant. Out of about 25 bites maybe 3 or 4 came up in huge 3 inch round lumps. The rest are like large blisters. I look like I have a nasty disease! Rather oddly, my 15yo niece had a mozzie land on her arm, it bit her then dropped dead!! I may donate her to medical research on behalf of my fellow sufferers. I am type B- and have slow clotting blood (I am described at the blood bank as ‘a persistant bleeder’!?!?). I’m a moderate drinker and have a average body temp of about 98.2. I feel the heat a lot more than the rest of my family, so maybe body temp is a factor.

    Michelle, September 30, 2011 at 12:24 pm
  216. Anyone else notice a good portion of the idiots who made claims of “well, I’m an O and never get bit” or “my family is this, and always get bit” — seemed to all miss a KEY POINT of the article. It’s not ONLY whether you’re an O or an A, but is also effected by if you are a SECRETER or not!!! If you don’t secrete your blood-type through your skin and breath, then at least in those cases, it’s not your blood-type attracting the mosquitoes! (Scientists can be so silly sometimes — in the cases of those who are non-secreter who aren’t getting bit, are they possibly putting out another ‘smell’ or signal (like temp?) that is attracting them?) You can find out if you are a secreter with a very simple test that swabs your spit.

    I find the whole conversation fascinating. I have a room mate who follows Dr. Dadamo’s “Blood Type” diet. It makes a lot of sense if you figure man and mosquitoes would have developed along the same evolutionary paths — as part of predator/prey. Those with the younger blood-types who don’t secret may have found an evolutionary way to reduce bites and the infections the biters carry.

    Rebecca, October 10, 2011 at 2:51 am
  217. well, i wish someone would find a cure before i get some deadly disease or something! This whole topic is fascinating- and by the way whoever made this website…it’s embarrising how you put a crane fly on here, however, i think i am AB possitive and i get bit ALL THE TIME! And not only do i get around 10-12- or more! I get them swollen sometimes too( and i mean huge ) Questions…i would like to know is the mosquito prehistoricly old? has it evolved? AND what’s the best reppelant you can recommend for me??? Note: i am a runner, cold hands, and active person:) TRUST ME DOC! I NEED HELP!

    alexandra nockengost, October 10, 2011 at 7:50 pm
  218. I am B+ and mosquitos prefer me over my husband who is type O and rarely gets bitten. I saturate myself with OFF, reapply it frequently, and still get bit. This has puzzled me for years. It make me feel alot better knowing that scientist are just as puzzled as me.

    Amber Million, October 17, 2011 at 4:30 pm
  219. It´s end of October in Germany, we´ve had the first frost and I´m still sleeping under a mosquito net, because the suckers will find and bite eyelids, temples, cheekbones and fingers exposed under the blankets. I´m B+, my husband is A+ and they ignore him completely. We eat the same diet and are both fair skinned. My brother´s family uses my nephew as mosquito repellant, when he´s around they don´t get bitten.

    I have noticed that bathing the bites in Lugol´s iodine solution reduces the swelling immediately and keeps the itching at bay for 8 to 12 hours, when I reapply the iodine. No more welts and no more bleeding sores for me, and the bites fade away within 48 hours, but I wish I could repel them like my husband.

    My mother always used to be plagued by mosquitoes until this year, when for some reason after 85 years of being bitten, she seems immune.

    Thanks to all who posted remedies. By the way, the Lugol´s stops acne in its tracks, too.

    Anita, October 25, 2011 at 4:19 pm
  220. Let me throw a monkey wrench into the blood type theory. When I was a kid I was bitten mercilessly. The older I got, the less I seemed to attract mosquitoes. While to the best of my knowledge my blood type hasn’t changed, I no longer get bitten. They will sometimes land on me, but rarely bite, and when, on the off chance, they do, I don’t get the itchy welts from them. I always like to say my body built up a tolerance, or started creating some repelling scent or maybe it was the change in hormones that come with age. Any ideas?

    vickie, November 21, 2011 at 12:41 pm
  221. I am B+ and I about everyday get at least 7 mosquitoes bites each day at home. My mum and bro is O and my dad is B+. And i am the only one get bitten by mosquitoes everyday that I’m bitten by mosquitoes.

    Milo, January 6, 2012 at 5:13 am
  222. I’m a B-, and so is my friend. We both always get a tremendous amount of mosquito bites all the time, and no one else gets bitten but us…
    So isn’t it B- that attracts mosquitoes more???

    Katie, January 7, 2012 at 9:43 pm
  223. I managed to get 68 bites on my legs over the course of a 3 hour period! Most people only got a few or even none! Not sure what my blood type is, but nevertheless I’m sure I wasn’t the only person out of the bunch of 40 people with my type.

    Corinne, January 13, 2012 at 3:17 am

    SIRM, January 31, 2012 at 7:50 am
  225. Well I am an AB- blood type and even when with people who are O blood type I am ALWAYS the first to get bitten and also have local reactions to the bites.

    Phee, February 4, 2012 at 7:43 pm
  226. I wonder as to why the size of the mosquito bite varies.
    Does it depend on the species of the mosquito or is it the amount of time it spends sucking on you’re blood?

    curious, February 20, 2012 at 1:56 am
  227. The illustration is not a biting(female)mosquito, if it’s a mosquito at all; it looks like a crane fly to me.
    My husband and I are both O+; bugs like him a whole lot more than they like me.

    ccrow, March 1, 2012 at 8:47 am
  228. I have O+ blood and rarely get bitten, while my mom & sister (both A+), get eaten alive!

    Lisa, March 13, 2012 at 7:15 pm
  229. Both my wife and I are A+. She never gets bitten, whereas I am every mosquito’s favourite – so kiss the blood type theory goodbye! Attraction could have something to do with temperature, but they seem to find me even when I am on not hot and sweaty. So more likely the “fatal attraction” is associated with chemical markers (odours) emitted by the body – confirmed by some recent website articles.

    Cees, March 31, 2012 at 6:01 pm
  230. Give me evidence and repeatable tests.

    Evidence, April 10, 2012 at 11:10 pm
  231. I’m A Negative blood type, I’m allergic to mosquito bites, the first time I went camping I was rushed to the ER and the people thought my parents beat me, I’ve had my eyes swell shut. All starting from when I can remember, I don’t think it is specific to RH or blood type, they just like blood, certain smells and colors. Some moreso then others.

    katie, April 22, 2012 at 1:32 am
  232. DAMNNNN….!!!i am related to o+ but i was always bitten by mosquitoes

    sravya, April 22, 2012 at 5:37 am
  233. I live in Florida, but I used to get bitten a lot when I lived in New York also (but not as much). Type 0 blood. I get bitten a lot in my car. Almost all of the bites are on my right foot — the one I use on the gas peddle. Perhaps there is something to idea that they bite you where/when you can’t defend yourself. Also, around my ankles is about the only place exposed because where I teach is absolutely freezing and I wear long skirts and slacks with my arms covered all the time.
    I hope they resolved this issue!

    Arna, April 24, 2012 at 5:04 am
  234. im very curious because my blood type is O- and they do not bite me at all my friends and family have to go out wearing the bug spray in our mosquito infested florid back yards and i never have to and never get bitten. i used to when i was little but i cant tell you the last time i was bitten. was wondering if it could be and underlying thing and maybe not just based on blood type. we’ve tested it not one lands on me. even when i was pregnant with my daughter not one bite. can anyone help me understand why. not that i would rather them bite me just wondering why I’m different.

    Debbie, April 25, 2012 at 8:52 pm
  235. Mosquito bites to nurture its coming generation.For this reason they do need blood,so they do search for it . Naturally we are bitten by them, whether O or any blood type.I am now sitting with my room mate , he says he is more prone to it and he is AB+ but I am 0+ and say that I do also get bitten by it frequently.
    Mosquito wants blood , so it uses many ways to find it. Here we have to search the ways to escape out of it.

    PKA Gafoor, May 2, 2012 at 9:07 pm
  236. I am blood Arh positive and get eaten all the time,mosquitos,black lfies u name them while my husband is type 0 and we can sit side by side on the deck..he never gets bitten but i have to go inside or be devoured..I am sick of insects.

    jean leshane,canada, May 12, 2012 at 12:09 pm
  237. I am a Blood Type O and I don’t get mosquito bites at all. Does that mean I don’t give off those scent of Proteins? Is that a good thing for me for not giving off those scent of proteins or is that bad?

    Jaw Wan Ling, May 13, 2012 at 8:45 am
  238. i m blood type B+, i always get bitten by mosquitoes, even i cant sleep well bcoz of mosquitoes

    reshma, May 17, 2012 at 6:39 am
  239. that was awesome , i live Trinidad and in here mosquitoes are always biting your ears ,shoulders,back,neck or under your feet. This will be useful

    kereem butler, June 4, 2012 at 8:28 pm
  240. I HAVE not got a mosquitoes bite. ONLY WHEN I WAS 4 OR 5. It was very pain full i got 1 i was screaming. So when it was hallowen my mom gave me cotten candy. I was happy when hallowen was over. I had moquitoes bites it was small but it hurts.Iwas going to school and it was itchy but i avoid it. so. When it was my birthday i turened 6 i think so who care back the real thing.

    Heather, June 4, 2012 at 10:29 pm
  241. I am A+ too and genetally get eaten alive, so I have concocted up my own insect repellent which works well. I have a bottle of almond oil ,mixed with natural citronella, it stops these friendly loving critters from biting. the smell of the therapeutic oil and almond tends to get their little legs or beeks stuck that’s if they get that close. The citronella always makes me feel on holiday now when start mixing it up :-)

  242. I was wondering why I got bitten so often, while others around me didn’t. I guess it’s due to my blood type being O. Dammit :(

    JBarros, June 11, 2012 at 8:04 am
  243. I have just returned from a week in France where I was bitten countless times, all over my body including my face. My blood type is AB+. My husband and children were not bitten at all. I don’t drink or smoke, I did spend a lot of time moving about. I had repellant on and burned a citronella candle in the evening, they still got me in my sleep though.

    Jackie, June 13, 2012 at 9:13 am
  244. I have been wishing for the answer to mosquito bites for years. I’m not sure this article helps much. I am blood type B-, don’t drink, not preg etc. but mosquitos like me more that anyone I have ever heard of. On an outing once, the other members of my group had a bite or two and I was literally covered, I had hundreds or even thousands of bites. Covered from head to toe as bad as chickenpox. Five min outside is enough for me to receive a dozen bites, even after dousing myself with strong DEET. Please find a real answer to this question!

    Samantha, June 21, 2012 at 10:52 am
  245. That is not a picture of a Mosquito, it’s a Crane Fly.

    drew, June 27, 2012 at 11:50 am
  246. I never get bitten by mosquitoes. I am 1/16th Choctaw Indian, and my grandfather that was 1/4th Choctaw always told me that mosquitoes didn’t like Indian blood. My blood is also type AB. I’m sure the Indian thing is just an old wives tale (or Indian tale), but that’s what I always tell everyone on the 4th of July (when out watching fireworks) and they are fighting off mosquitoes, and they’re not anywhere near me! I’m 65 yrs old and only been bit about 4 or 5 times in my life!

    Maggie, June 27, 2012 at 6:24 pm
  247. The picture looks like a May Fly to me. Any way I’m type O positive and I’m one of the unfortunates that get bitten by mosquitos like there is no tomorrow. Actually I just discover that the black flies from the NY love me too and those bites HURT!!! I would pay big money to change this mosquito problem

    Edy Johnston, June 27, 2012 at 8:30 pm
  248. Its funny that no one has noticed the photo of the mosquito looks alot more like a Crane Fly or otherwise known as “mosquito eater” where I grew up. Kind of a hilarious mistake I think.

    Smithy, June 30, 2012 at 2:53 am
  249. Haha too funny I read at least half the comments and scrolled to the bottom to post my comment only to notice that I missed the previous posts noting the mistake.

    Smithy, June 30, 2012 at 2:56 am
  250. I am type O positive. I always get bit by mosquito’s, while other seem to not get bitten. My body temperature is always warm and I always sweat all over my body, so I believe this is why I get bitten so much. I get bitten, even with repellent on. My bites swell up and itch like crazy for days. I was told by a friend of mine that he and his son use to get bite all the time. They started taking vitamin B daily and now never get bit. I was trying to find out about this, that’s how I ran across this web site. Does anyone no if the vitamin B consumption is true for stopping mosquito’s from bitting?

    Maria, July 2, 2012 at 8:08 pm
  251. i get bitten alive too i hate staying out side after dark . i have put on bug spray and it dosent work i get bite but no see ums too ouch. my dad and i have type o blood and my mom dosenot she dosent get a bite on her its not fair.

    lisa sipes, July 3, 2012 at 5:30 pm
  252. Do these findings serve as answers to the ways vampires choose THEIR victims?

    Kinerina, July 14, 2012 at 2:53 pm
  253. I am not really sure what to think of this. My blood type is A+ and I have never met anyone in my life who gets attacked by mosquitoes like I do. If I go outside without repellant on I will get bitten 5 to 10 times in just a few minutes. There was one specific time I was outside for less than 5 minutes and had to run inside because my legs were burning so bad. I had to have a friend put hydrocortisone cream on each bite and we literally counted 30 bites exactly! I am not exaggerating! The only thing I can think of is that I am always really hot. I am naturally hot blooded and like to keep my house like a meat locker. That is really the only thing that I can relate to with this study. Either way I would love to know what I can do other than covering myself with DEET every time I go outside. I really despise mosquitoes and have no idea what their purpose is on this planet other than to drive me insane and to spread disease! If anyone has any ideas please feel free to share.

    Cheri, July 16, 2012 at 8:37 pm
  254. Btw, I take B vitamins on a regular basis and that doesn’t do a thing for me.

    Cheri, July 16, 2012 at 11:31 pm
  255. I get bit an insane amount. Unlucky for me, it seems that a mosquito found its way into my bedroom. I woke up this morning with 15 mosquito bites. My partner? Not one. Based on this article, he should definitely be the one being bitten more..not me! For some reason, my normal body temperature is a chilly 96.8 while normal is 98.6 (and I’m fairly sure that my partner’s is higher than that! He’s always so hot!) So why are they making a nose-dive toward my skin, not his? Also, my partner is much more burly than me, with huge nostrils! I have no doubt that he exhales more carbon dioxide than I do. Curiously, he’s also O, while I’m not.

    This mosquito attack isn’t just a one-time, random event either. During a normal summer, I’ll maintain an average of 10-15 mosquito bites a week, and rack up an impressive 30-50 bites from one out door adventure (like camping out, going swimming, or going on a picnic)–and that’s with OFF!

    I’ve also noticed that, lucky for everyone else, I seem to act as a mosquito repellent for others. As long as I’m around, no one else will be getting mosquito bites–they all go straight for me!!

    Oh god, I don’t even want to know what will happen to me when I get pregnant..

    Sarah, July 17, 2012 at 9:28 am
  256. My blood type is O+ and used to get bit all the time when I was a young adult, but haven’t been bitten much in the last 10 years or so. I was outside after dark 2 days in a row. The first night, I wasn’t bitten at all, but didn’t drink any alcohol. The second night I had 2 beers and I counted over 50 bites on my ankles and legs, with a few cluster areas of 4-5 welts in close proximity. The welts didn’t appear till about 24 hours later. Three days after the feeding frenzy, they were extremely red and itchy, and drove me crazy! Also, I live in an area of the USA that has been one of the hardest hit by the drought of 2012; somehow they are able to breed and mass produce without much water. So, using my example, I believe blood type and alcohol consumption increased my tastiness to the little beasts. Oral Benedryl and topical Cortizone 10 Plus have helped a little, but I guess time and less scratching will be the ultimate healer.

    Pam, July 17, 2012 at 10:01 am
  257. I strongly believe the mosquitoes are attracted to acidic PH balance. Drinking alcohol makes your body more. So will eating acidic foods and not drinking enough water. People who are overweight also tend to be more acidic in PH. I think its those who have a more alkalized blood that are the ones the mosquitoes dont want.

    End, July 19, 2012 at 10:08 pm
  258. I don’t believe in the whole blood type theory. I’ve been getting eaten alive by mosquitoes this summer, but only during my menstural cycle shortly after ovulation. I know that body temperature rises only a bit, but this seems to make the difference since I seem to become the main course for these bugs!!!

    Judy, July 25, 2012 at 3:35 am
  259. I find this article complete bogus.

    I came to India this summer and I am being eaten alive. I have B+ blood and so does my mother. She doesn’t have a single bite. And the reaction I have to the bites are these big bumps on my skin that I can’t help scratching. I have counted more than 50 bites while my mother has like 4. My dad is a O+ and he only got bit like 5 times during the whole summer. No one seems to get bit except me, even people with the same blood group! It is rediculous!

    Sanjana, August 1, 2012 at 11:39 pm
  260. I am flabbergasted at all of the comments and do not understand why I read like 15 of them, or why so many people commented. One thing is certain though mosquito’s suck. I hope this helps bahahahahah

    jibbering ferry poop, August 18, 2012 at 7:39 pm

    Ashleyyyyyyyyyyyyyy:D, August 21, 2012 at 3:12 pm
  262. This was very interesting since ive always wondered y i am always bitten and ive tried everything to keep them off of me and i have o+ also so maybe that is why but im always getting bitten in my household

    Crystal, August 24, 2012 at 4:17 pm
  263. I get at least 30 bites a day even when wearing repellent. My blood type is O-. My family doesn’t even bother with repellent when I’m around, because all the mosquitoes will leave them alone and come after me. We have the little Asian tiger skeeters. I don’t drink, and am not “less defensive”. I am at WAR with mosquitoes! I get bit, but they DIE!

    blah, August 31, 2012 at 10:10 pm
  264. my wife and some friends react badly to mossy bites and i have always said i never get bitten but the other night i saw a mossy land on my arm and i watched it stick its long thing in me and feed on me .thier was no mark and no swelling after,i think i get bitten all the time and just dont know about it

    dean idiens, September 1, 2012 at 7:42 pm
  265. I am a+ and my body temp. is 96.8 I get ate by a lot of bugs all the time. If I scratch at them, I get bit more often, till I am covered in them. Repellant does not work. I wish someone could help with this.

    Nancy, September 3, 2012 at 10:27 am
  266. They have no answer. A+ , repellant works a little, alcohol effects nothing, body temp, nothing,……..No answers

    Rich, September 5, 2012 at 7:44 pm
  267. I get bites all the time, I could be outside for just a few minutes and I see them landing on me. my blood type is A/b and I do drink alchol and do smoke. Im not sure if that has anything to do with the biting. I was told that because my skin is dard that bugs love me. not sure why. I don’t love them! every summer until the first frost, when most bugs in the east are killed off, then I’m free of bites. I love the fall and winter, just for that reason. Does the earth really need the insect Mosquitos? What are they good for?
    Not liking the bite in Maryland

    Paula Procyshyn Chomko, September 11, 2012 at 4:35 pm
  268. I am type A+ and always get a LOT of bites, even if I walk outside for just 2 minutes! Worse in early a.m. and mid-late afternoon. I wear NO fragrance, my soap is unscented, as is my deodorant, shampoo, etc. I have found that Cutter helps a good bit. I’m convinced that there is something about me that attracts mosquitoes quickly. I can be standing next to other people and the others rarely get bitten compared to my many bites.

    MargaretC, September 13, 2012 at 7:02 pm
  269. I read once that there was research done on pheromones, and that genetically people produce a natural odorless repelent, but a few actually lack this natural repellent. But on the blood side; there may be a factor most of you are overlooking, is that even though you are A+, or whatever, you may be AO, meaning you are carrying perhaps a recessive O blood type. For example my father and mother were both AO, but show on blood tests A+; and they had three children with A+ and two children with blood type O. So even though I am A+, I still get eaten alive out of a group of 10 people who get only a couple of bites, and it may be because I also carry blood type O.

    Yellow, September 19, 2012 at 1:44 am
  270. I always get bitten and I have an allergic reaction so it’s miserable so I came on this website for an answer …. I am more confused than ever … My blood group is O but I am always cold …. I do drink alcohol but am bitten even when I don’t …. This time I took antihistamine a fortnight before my holiday … Yes I still got bitten but have not reacted as badly …. In the past I have spent the night in the shower & the itching has driven me mad … They swell up so much that I look deformed … I thought holidaying in september wouldn’t be so bad … I think it is just the luck if the draw … They either like you or they don’t

    Cerys, September 19, 2012 at 5:36 am
  271. I am O- and I am a mosquito magnet. My theory blows everyone else’s away…we who get big the most, are just the sweetest….lol

    crystal berardi, September 21, 2012 at 12:11 pm
  272. *bit the most (not big)

    crystal berardi, September 21, 2012 at 12:12 pm
  273. When I was young, I often had allergic reactions to mosquito bites and so my father (a physician) sent me to camp with bottles of high dose B vitamins. He claimed the odor they caused on the body or the blood repulsed mosquitoes. When I took the vitamins regularly, I was not bitten. Now, I find that when I eat foods high in B vitamins, (whole grains) I don’t get bitten. Has there ever been any studies done to prove this theory?

    Marian Minkow, September 23, 2012 at 4:25 pm
  274. After Googling Why do I never get bitten by pet fleas, mosquitos etc…I still find after reading numerous forums, I am really none the wiser…I should be grateful I dont get bitten. But still really & truly would like to know why?

    Julie, September 25, 2012 at 7:00 pm
  275. I’m A+ and I get bit ALL THE TIME! I don’t think it has to do with blood type! I think it has to do with the signature scent that everyone gives off but like your fingerprint everyones scent is unique! Each scent is either sweet or bitter and mosquitoes love their sweets! Lol! ;)

    Lisa, October 9, 2012 at 10:54 pm
  276. I am in deep problem with mosquitoes bites. Every where I am. In the bathroom,toilet,bus,or car,taxi,even at work.imagine I teach,holding. An. Electric mosqitoes killer and a piece of chalk in the other hand.I am humiliated but I can’t do otherwise.please help.

    Zagabe PIPPEN, October 12, 2012 at 9:13 am
  277. my family and partner, dont get mosquito bites all the time than i do. even my lips, mosquitoes get attracted to it.. funny but seriously, im getting pissed off.. there was this time that my partner could even think twice if ive been really bitten by mosquitoes wherein fact he have not encountered one.. until he saw my skin, almost no space for a bites

    liz, October 15, 2012 at 10:40 am
  278. The picture on this article is not a mosquito, but rather a non-biting crane fly (Tipulidae)

    D$, October 15, 2012 at 11:43 am
  279. Sounds pretty cool….. I’m blood type O and seem to get bitten all the time….. I was reading this article hoping to find out why I seem to ALWAYS get bitten when the very mosquito who is annoying me at night for some time lands on my iPod screen!! Whoohoo thanks guys. You gave me the opportunity I needed to kill that stupid mosquito… And I learnt something too!!!!! :D:D

    Algie42, October 29, 2012 at 6:51 am
  280. Hey so thanks for this article. I was just suffering from multiple mosquito bites.
    My mother said that i had a rare blood type,somewhere like O-, so then I saw like, two mosquitoes on my windowsill DEAD and my mother said that they probably ate themselves sick(is that possible?!)So yeah, now I know why they came after me, not my siblings or my parents, it’s weird we all have different blood type, except for me and my dad’s

    Rene, November 2, 2012 at 8:25 am
  281. I am b+ but i always get bitten by mosquitoes more than my friend who is an o so why does this happen????

    Raven, November 18, 2012 at 11:40 am
  282. that is not a mosquito in your picture. it is a Crane Fly.

    matt bigos, November 22, 2012 at 12:26 pm
  283. I don’t think it’s the lack of resistance thing. I get bitten multiple times every night as I sleep. My partner sleeps beside me and never gets bitten. Neither of us flails about and we both are just as covered as each other. I am a fair bit smaller than he is so it’s not availability either. I don’t know my blood type though!

    Professy, December 3, 2012 at 10:16 pm
  284. My family and I do not get bitten by fleas or mosquitos, we are type A positive Blood. I also have arare genetic dease as probably does my family, Primary Immune Deficiency Disease. I have low IGA IGG AND IGG. I get immunoglobulin infusions every 4 weeks. I was looking at COLOSTROM in brest milk of a new mother and discovered the first 3 to 4 days that is what the baby is getting to keep him immune to diseases, Can anyone tell me if I have hit on a connection for this disease that doctors do not seem to understand?.

    Colleen Fadollone, December 16, 2012 at 12:12 pm
  285. http://www.llli.org/faq/colostrum.html This is the info on breast milk from previous posting.

    Colleen Fadollone, December 16, 2012 at 12:26 pm
  286. this is ridiculous. When i’m healthy I get bitten, but when I get the flu or cold even if I’m surround by mosquitoes flying around me none of them bite me. So it is something in the breath that attracts them and also on the blood. I believe also in the food we eat that makes our blood different. I’m type 0 and so is my partner but she eats more spicy food than I do and never gets bitten, where in my case I eat less spicy and get bitten always. These mosquitos know me and bites me even if other people are next to me. So when I’m sick even if I go out and sleep I never get bitten. The breath and the blood-calorie? blood-flavor? is what attracts them.

    nonsense, December 23, 2012 at 11:17 am
  287. Try living in Australia, my wife & I as well as our oldest daughter get smashed by mozzies, yet our youngest at 9 has never been bit? From the responses do far I will try vitamin b -1 tablets & applying mouthwash to all exposed areas of the skin.

    John, January 12, 2013 at 12:41 am
  288. The blood type theory is bunk. I am AB+, my partner is O+, and I am ALWAYS getting bitten. He never gets any bites. It is ridiculous. No matter who I’m with, it’s always me!!! Why?!?!?! And people look at me as though I’m crazy when I start scratching and mosquito bites start appearing, because no one else is affected!!! Frustrating!!!

    Am, January 18, 2013 at 2:27 pm
  289. thanks. needed the information you gave for my project :)

    gka, January 19, 2013 at 4:04 am
  290. Yup, its still me. i am a B type but didn’t get bitten, why? please answer

    gka, January 19, 2013 at 4:05 am
  291. i can say this is a good website and will recommend it to friends!

    gka, January 19, 2013 at 4:06 am
  292. relax people, every living creature needs feeding…..

    essius, January 23, 2013 at 12:09 pm
  293. My son has epilepsy and takes Tegretol tablets. He never gets bitten, the Mossies land on him but fly off again. May be something in the Tegretol they don’t like.

    Ray, February 16, 2013 at 10:58 am
  294. I am AB and I always get bitten, my husband is B and never does. I am thinking it might have more to do with what you eat. I eat only high starch vegetables. I hate the rest. My husband loves them all. Tomatoes the best. He will eat tomatoes every meal in the summer. He grows his own. So I wonder if the acid in the tomato might have something to do with it. I have been thinking about taking vinegar pills and garlic pills this summer to see what happens. Wish me luck.

    Nannette, February 27, 2013 at 12:12 pm
  295. Can’t we give the mosquitoes a flu to suppress the AgOr1 receptor in their olfactory which responds to human sweat odors?? Or for an instance, cant we spray something on them that smells like the chems in our sweat and turns them attracted to each other? Like..canibals?? P.S. M not a scientist.. Just a thought.

    rajeev das, March 6, 2013 at 2:48 pm
  296. wow no wonder why i get bitten so many times… im blood type O

    Hao, March 10, 2013 at 2:24 pm
  297. I’m O+ and I’m permanently being eaten alive! Most repellents dont work for me. My fiance will lay next to be and not a single bite. I can cover myself from head to toe and they will still find a way in to bite me and still no bite on Mr. Fiance. Totally unfair! They really should just wipe out the species. Would do most people the world of favours!!

    Cara, March 12, 2013 at 4:14 pm
  298. The best way to stop the itch from a skeeter bite, as told to me by a doctor. Turn on your tap to warm water and put the bite area (whelt) in the water. GRADUALLY increase the temp of the water until it is all but unbearable (don’t burn yourself) and hold under for about half a minute. This will break down the proteins from the “skeeter’s” saliva, which causes the reaction and itching. This really works for me, I hope it does for you too.

    Mack, March 31, 2013 at 4:58 am
  299. I’m not O but I keep getting bit all the time. I don’t mind mosquitoes though (death penalty seems too harsh just for some itching, and they had to do it to live). I’m just curious to know more about what attracts mosquitoes.

    Neo Jing Ci, April 18, 2013 at 9:55 am
  300. Hello! Would you mind if I share your blog with my zynga group?
    There’s a lot of folks that I think would really enjoy your content. Please let me know. Many thanks

    getting rid of bed bugs news, April 22, 2013 at 8:56 pm
  301. Ive been bitten loads over the years, an i too have bad reactions to most ov the bites as itchy as they are you really do have to try not scratching them which is pretty hard to do. I have red hair an fair skin an very hot blooded . I think its a mix ov things that the mossies go for . i give off an irresistable aroma to the mossies wether that be hormones or my blood marker or just the scent ov me i dont know, but i have noticed over the years as im getting a bit chubbier an ive a lower immune system i dont get bitten as much. they say that fair haired people have thinner layers ov skin but more ov them than darker skinned people , that wud also make it easier to the mossie to bite you . So my theory is Aroma from the individual,scent ov blood type or bodily secretions,body temperature , ure diet, an maybe ure immune system bein high or low.I always use the Autan spray to repell them especially when i used to go abroad but i get bitten just as easily here in Britton.So if i go to a place that is near lakes or sum form ov water an lots ov trees an shrubbery i cover myself in Autan even if theres a small spot not covered the mossie will find it, because ov all the messages my body sends out that the mossies respond too. Hay wot can i say at least im irresistable to sum living creature in this world, lol…….

    Paula, April 28, 2013 at 6:50 am
  302. Oh yeah forgot to mention my blood type is O+ as are my son an daughters, my son has red hair an fair skin hes a teenager an the mossies luv him , my daughter has olive tone skin an its rare she gets bitten , shes recently had a baby so wether thats changed the dinamics ov her gettin bitten by the mossies or not ill have to ask her. I hate the bloody creatures an wot they do an wot they can cause desease wise, but the thing is we really shudnt wipe them out as they are a part ov the food chain there are animals that live off the mossies an try to keep the numbers ov mossies down, i agree that they are getting out ov hand all over the world,but the only thing we can do is keep finding ways to protect ourselves against the things . Its the individuals signature a mix ov things from the person that attracts them to a person, oh an its only the female that bites you…..Autan get loads in it works for me guys.

    Paula, April 28, 2013 at 7:07 am
  303. “…and so is evolutionarily predisposed to biting lazy or incapacitated prey (reference drinking above).”
    I don’t think mosquitoes have the ability to judge a person’s laziness or inability to fight back based on whether they are drunk or not..

    Jen, April 29, 2013 at 7:15 pm
  304. I’m AB+ and literally eaten alive.so continue the research !!

    Jim Atkins, May 7, 2013 at 5:56 am
  305. I am A+ and considered a fine cuisine to these biting pests. After being tested for which bee enzyme I am allergic to I was told by the dermatologist that my body omits an odor that attracts bees and bugs. REALLY? I already knew that. I can be in a crowd of fifty people and I am the one that the bees and bugs bother. Deer flies, which bite, are attracted to me and rarely bother the person next to me.
    One thing you can do to get revenge with a mosquito is when one lands on your arm let her insert her sucker. When she starts to drink tighten the muscles in your arm as hard as you can. She will be unable to remove her sucker and will pop and leave a small amount of blood on your arm that she intended to steal. Works every time and is fun to watch happen!

    Steven, May 21, 2013 at 10:50 pm
  306. The blood group theory must be correct. I am AB+ and have travelled to many mosquito areas, I have not been bitten once. My girlfriend was eaten alive during our last holiday and she is O-.

    Jason, May 24, 2013 at 5:24 pm
  307. Try just drinking tonic water or beeter yet Vodka and Tonic, mosiquitos leave me alone and i attribute it to the quinine in tonic water, true tried and tested in the jungles of Honduras

    Chris, May 30, 2013 at 11:13 am
  308. blood type theory is probably wrong there are a lot of post with O types never getting bit my friend is almost 40 and never bittin once in her entire life and is O type.

    will, June 1, 2013 at 9:53 pm
  309. my friends not a secreter either i dont think

    will, June 1, 2013 at 10:29 pm
  310. I am type O+ and I rarely get bit by mosquitoes,spiders and fleas but my partner who is Blood type A- and he would be bitten by all of them.

    Kristen, June 10, 2013 at 11:20 am
  311. We vacation in Montana and were eaten alive until we discovered Permethin soaked clothes. Google it. It really works. Last year the bites went down from the year before 40-80 down to 2-4 in 3 weeks. we’re going back again this year and will post the results.

    Dave, June 16, 2013 at 5:49 am
  312. The people that think that some people dont get bit more than others are idiots. These people are obviously the ones that dont get bit that often. I get eaten alive by mosquitos while my brother and friends who are sitting right next to me are unaffected. I am a big dude, and i sweat alot. So i was wondering if other people who sweat alot also get bitten alot. i thought that may have something to do with it. my brother is bigger than me but doesnt sweat near as much.

    brian, June 28, 2013 at 6:36 pm
  313. This is a test for the researchers. Could it be that the monquitos have a sence of determining which pray is healthy and which pray has either a terminal disease and chooses which pray to go after. It wouldn’t hurt to test this theory out… Look forward for comments.

  314. It’s only in the last 4 or 5 years that I am being bitten. This year is the worst of the lot, my knees down are destroyed. The bat population is dying resulting in more mosquitoes as one bat eats thousands a day. It’s also dangerous how Bill Gates is utilizing the mosquito. Those chemical sprays are cancerous so I would never use them. I just ordered Byte Back from healthwyze.org hoping this will solve the issue.

  316. I drink a lot of beer and get eaten alive. Maybe that’s it.

    Godsmack, July 7, 2013 at 8:03 pm
  317. In the mid-50s, I was sent to Singapore. The mosquitoes were a pest initially, until I was told to drink a pint beer before going to bed. After that, no more bites. Newcomers were warned immediately of this. Since Singapore is very hot and humid, you tend to sweat a lot, so the smell of the beer came through your skin, and the mossies didn’t like it.

    Derek, July 8, 2013 at 11:32 am
  318. I’d guess mosquito attraction differs for loads of reasons, including pheromones, skin microbes, blood microbes (bacteria, viruses, fungi, parasites, protozoa, prions, etc.), hair microbes, mineral levels in the skin/blood/body/hair, antibodies (wouldn’t be surprised if they made a mosquito vaccine some day), the food you eat, your immune function, how much you exercise, how old you are, hormones, sex of the individual, genes, aesthetics, skin texture and toughness, your thoughts about mosquitos, herbs, personal care products, metal poisoning and the lack thereof, etc.

    Anyway, mosquitos bit me a lot as a kid, once in a while as a teenager, and hardly ever after that. I’d say it’s not always the same per individual. How noticeable the bites were (swelling/itching) seemed to correspond to how much they bit me. They don’t seem to swell anymore. It could be a coincidence.

    I have O positive blood.

  319. I think B vitamins are supposed to help, as well as raisins. Maybe see if fenugreek (internal), garlic and sempervivum (hens and chicks) help, too. Fenugreek is just a suspicion, but it really changes your smell (which could indicate things besides smell).

    Catnip supposedly repels mosquitos. It often grows as a weed.

    Mark, July 9, 2013 at 6:50 pm
  320. Anyway, I’m just ranting. I don’t know of this helps.

    Mark, July 9, 2013 at 6:52 pm
  321. I am mid 30s indian…. When I was a kid.. I NEVER used to get bitten.. my annual trips to india….. I could see one of the suckers land on my arm.. rest and fly away… since the last 8 yrs… … urgh!!!>… 2 yrs Went to india ago and cuba a few times too I was eaten alive.. here in sunny England… I get bitten…. everywhere and anywhere… its horrible.. skin goes all red…. bumps and it gets REALLY SORE almost like a reaction… ive tried a lot of sprays etc…. no idea… I thought being Asian i’d b used to them and them to me !!!! battle continues!!!!

    Kelly, July 10, 2013 at 8:29 am
  322. I never get bitten even when they land on me….figured they might be biting me but I am not allergic to them. I pretty much as far as I know am not allergic to much of anything. I also don’t get rashes with poison ivy or oak…mosquitoes buzz me alot in the early evening when I am in my pool. No bites

    Bea Loesch, July 12, 2013 at 7:44 am
  323. My blood type is O-. Rarely get bitten by mosquitoes. When I was a little kid it’s totally different, I got bitten all the time. One day I decided not to kill or harm mosquitoes while they are on me and after several years it gradually reduced the incidents of bites.

    Lasantha, July 15, 2013 at 11:24 pm
  324. Well, I am a healthy 74 yr old and have NEVER been bitten by a mosquito,}they will sit on me periodically} but will not bite, no matter where I am or the conditions of the weather, night or day…I also have never had chigger bites even when everyone else is in the same area. don’t go to doctors, so do not know what my blood type is. Maybe I should find out, but if emergency comes up and someone needs donor, I will get tested. I feel blessed in so many ways. have a good day and don’t let the bedbugs bite either…

    emma, July 18, 2013 at 9:32 pm
  325. I get bitten a lot by mosquitoes and
    I don’t know what blood type I am but I’m pretty
    sure I’m blood type O. I think I’m more a B positive
    So I think that blood type O rarely gets bitten

    Random Person, July 19, 2013 at 4:27 pm
  326. I don’t know what blood type i have but i never get bitten. ever. i’ve had about 5 bug bites in my entire life and i’m not kidding. i think it has something to do with my blood type, but i don’t know what it is.

    Faith, July 21, 2013 at 5:52 pm
  327. I am type O+. I get bitten so much that I honestly canont go outside in the evenings. My ankles and legs a itching so badly I can’t focus. Once i get a bite, I itch for 3 weeks constantly. My wife likes to sit on the patio and enjoy the view. I cannot go outside. Bug spray like deep woods off does not work for me. I have a can of pure DEET from the army and it does not work. I spray my yard, burn citronella, I even carry dryer sheets in my pocket. Yet, when I am outside I am the only one getting bites. AHHHHH! haha

    Paul, July 23, 2013 at 11:29 am
  328. thank you a lot thats why i got bit but

    Viviana, July 25, 2013 at 5:16 pm

  331. I went on a camping trip to the sand dunes with some friends, and i ended up getting 40 bug bites just on my face and probably even more on my body. One of my other friends also got bitten quite a few times on his face, but not as much as me. The other three friends got at least one bite each. I didn’t understand why, but now reading this article i realized it was probably because i have O- blood.

    Jessie, July 30, 2013 at 3:08 pm
  332. I got a place in a small town with many mosquitos around ( good nature area! ), i went there 2 last days , and specially with hot summer nights (25ºC and +), the place gets infested by mosquitos . I was with a friend ,and we got different results in hell bites.
    Myself got 0 bites after 2 days there and around coupled 10-12 hours night-uptime, the first night didnt use repelent , and 2nd night i did use for the bugs not even land on me,just 1 or 2 landed in about 5 -6 hour .I don’t have O blood type( i can’t at the moment confirm my blood type) , and this season i am very very tanned ,so my skin is really burning hot ( but doesn’t hurt ,just feel my temperature skin is much higher ,when tanned) so i suppose the mosquitos still land on me,due to skin emiting higher temperature, but they don’t bite due to skin emiting higher temperature .My other friend ,in around 5 First minutes of evening he got biten around 7-8 times, just right after 4 hours beach time , he had to run up for the repelent, which worked good ,but still got biten 1 or 2 more time later on (probably due to the repelent effect passed).
    Also, we both drank alot alcohol(red whine mostly )and i don’t know my friend’s blood type.
    When i was younger( from child to around 15-16) though i do remember i would get biten by mosquitoes specially when sleeping .thats what i can add !

    Bau, July 31, 2013 at 7:58 pm
  333. The photo you have used is not that of a mosquito. Looks more like some sort of cranefly (daddy long legs) to me.

    John Myers, August 8, 2013 at 11:40 pm
  334. im 22 and am always outside doing some kind of physical work around the yard and such. as long as i can remember i have been eaten alive so to speak by these things. my friends next to me are fine, but they see all these welts all over me and its itchy and so annoying. i just cant stand it. but this article has opened some light on the possibilities and im sure its my blood type.

    thanks alot :D

    alexander p., August 9, 2013 at 12:02 pm
  335. I don’t like that the author urges everyone to run outand buy bug repellant, aka DEET. This chemical is very dangerous to fish, birds and all aquatic life, not to mention human health. It can be found in 75% of all US waterways, including the Mississippi River. Make your own bug spray from essential oils the natural way. They work, smell amazing and are not harmful to human health.

    Hunter, August 17, 2013 at 8:49 am
  336. I have been searching in vain for information that makes some kind of sense about why I get so many of these nasty bites and my friends walk away with none. Just the other night I was sitting on my friend’s porch, there were 4 of us, within 5 minutes I had 6 bites and no one else had any! And like many of those who’ve posted before me, I get them in clusters, I had all 6 bites in a cluster on my forearm; it’s the most annoying thing and ITCH??? OMG!!! You just can’t imagine how bad it ITCHES, I want to scratch my arm right off…..I just wish someone could find something or someway to either get rid of them or a repellant that actually worked for those of us who suffer thru this.

    Christine, August 26, 2013 at 6:24 pm
  337. I have over 100 mosquito bites and I’ve been inside with one door open and a screen covering that door. Using Deet (between 27% and 40%) daily, a few times a day, can’t be good for me. I’m using Tea Tree oil to try to combat skin infections, but I am seriously worried about diseases now. I woke with at least 70 of these bites. Blood type 0.

    Fran, September 2, 2013 at 10:51 am
  338. Oh, I forgot to mention that mosquitoes are attracted to potassium so I do avoid bananas and anything with potassium during mosquito season.

    Fran, September 2, 2013 at 10:54 am
  339. I have finally stopped being bit by mosquitos. I finally found something that works for me, and for many that try it when I spray it on them. I use doTERRA essential oils, specifically TerraShield. It is an awesome blend of oils that really work well. Lemongrass is just one of the many oils in it that really repel many insects. I love it and always have it on hand. I just put some oil in a spray bottle (the travel sized ones they sell at the grocery store), I put 10-15 drops of essential oil, and fill the rest with distilled water. Then I just shake the bottle, then spray it. It is awesome, smells good, works great, and has no chemicals in it!! :D

    Tiffaney, September 16, 2013 at 12:34 pm
  340. Here is some more information on the oil itself:

    I get it here, in case anyone wants a link to it….

    Tiffaney, September 16, 2013 at 12:35 pm
  341. Yes! Finally something about irvine storage.

    fire inspector, October 18, 2013 at 4:27 am
  342. First: Your pic is not a mosquito, it’s a crane fly (Tipulidae)
    Second: There are countless variables that can contribute to a mosquito selecting one person over another. I don’t think that mosquito bite preference can be distilled down to blood type
    Third: Comment 338 – why do you think mosquitoes are attracted to potassium? Wouldn’t that make bananas alone the most attractive food source?
    Fourth: Comment 335 and 339: Lemongrass oil IS a chemical, and it is not natural to spray something like that onto your skin without expecting some reaction from it. Natural oils within the lemongrass are not there to make it smell nice for humans, they’re meant to irritate other animals, including insects, to prevent herbivory, but since mosquitoes do not feed on plants the oils may not irritate them as they would a caterpillar.

    Bob, February 24, 2014 at 7:32 pm
  343. This makes to much sense now I know why I get bit more than my friends! Its because I’m O-negative!

    Joe, February 24, 2014 at 10:34 pm
  344. I have another theory. Some people are allergic to Mosquitos and some aren’t. I am, but if I take an allergy pill I don’t even feel the bites and there’s no inflammation. So next time try taking a Claritin and feel the difference.

    Dana, February 25, 2014 at 10:45 pm
  345. Ok… im o n it sucks to be the target of mosquitoes
    Hate it arggh

    anonymousgirl, April 27, 2014 at 9:52 am
  346. I am from India with blood type B. I find the body temperature theory very interesting, since I have higher body temperature than others and get bitten by mosquitoes more than others.

    anon, May 19, 2014 at 12:27 pm
  347. I used to get bitten a lot. The bite marks swell up like the size of thick, hot quarters and itch something terrible. I’ve used every spray out there, lotions and creams. I also use Caladryl for the itch and Benadryl depending on how many bites and how itchy. My blood is O negative and my Dad was AB positive. We all got bit about the same amount. We live in Detroit and there’s a lot of marshy wet areas that are breeding grounds for mosquitoes. Since I’ve been diagnosed with diabetes, I’ve noticed I haven’t gotten bitten. I feel them land on me or kind of touch me for a moment but they aren’t biting anymore.

    Gina, June 1, 2014 at 3:59 pm
  348. I am O- and my husband is A+ and we NEVER get bitten. My daughter’s blood type is A- and she not only gets eaten alive but has HORRIBLE reactions to them. Last summer she had 3 going up her spine area and legs covered, they got so bad she had to be put on 2 different prescriptions creams and still took months to clear up. The ones on her spine hurt her, everytime she would move even the slightest bit she would break down in tears. Even covered up and using repellant she still somehow gets them bad! I don’t think blood type has anything to do with it. It seems like they’re reaching for knowledge they want so desperately that they pencil results that’s look and sound good.

    Christina, June 23, 2014 at 4:50 am
  349. Pretty much everyone has at least a mild reaction to Mosquitos. My daughter has taken Benadryl, used sprays, creams, prescriptions u name it and nothing makes a difference. I know every person is different and yes some with certain blood types might claim they get targeted more then others but there is obviously no certainty in any of this! Some people on here claim they agree with blood type theory and others say that’s wrong. Some people come on here looking for answers and get remarks like “take allergy meds see a difference.” What works for some, clearly doesn’t for everyone. It is very clear that they really don’t have any hard proof of why some get bit more then others. I have seen some people get very sick and have painful reactions to Mosquitos. I don’t find it funny, so for the people who read these posts and decide to be smart about what they write if u are not doing it to give advice to people or even just your input On the topic then maybe try not to write anything at all. Yes, it’s not that serious but it is meant to be informative and helpful to some people. SO…. There’s no need to try to be ignorant.

    Cyrus, June 23, 2014 at 5:07 am
  350. I am type O negative and have never had a mosquito bite in my life. Matter of fact all insects avoid me unless I happen to step on them or grab them accidentally. I’ve been hiking with friends that were being eaten alive even covered in Deet and I use nothing because I know I won’t need it. Also, my children are never bitten. Yes, And yes, I am quite pleased about it.

    John Halo, July 22, 2014 at 10:52 pm
  351. we are sooooooooooooo vulnerable when the mosquitos and flys and other insects arive in the summer months…….I am 69 and suffer every summer….I am ABpositive blood type…..Help me … does anyone have an answer of cure????

    Guadalupe Camacho, July 22, 2014 at 10:55 pm
  352. I am AB positive…………every year I suffer with mosquito bites….anyone out there.. has a cure???? I am the only one that gets bit in a crowd. Lupe. :(

    Guadalupe Camacho, July 22, 2014 at 10:58 pm
  353. I’ve always wondered why I never get bitten by mosquitoes, even when everyone around me is getting chomped away. I knew there had to be some kind of scientific based reasoning and I theorized it had to do with smells, so this is a very interesting read.

    amber, July 28, 2014 at 2:08 am
  354. I do beive everything on here because im the only one wth o- blood n the house and the only one that gets bit and they get bigger than the peoples with out o blood ..

    kara, July 30, 2014 at 10:57 am
  355. The blood type thing cant be right because I used to get bit all my childhood terribly. After I had my first child 29 years ago, I haven’t gotten a single mosquito bite. I figured it had to do with my chemistry changing after pregnancy. I just watched one land on me and move to 6 different spots trying to get a good spot. It never broke skin. I was just going to keep watching til it flew away, which is what they usually do, but my husband asked me to swat it to protect him….they love him.

    mary, August 3, 2014 at 11:04 am
  356. Straight up couldn’t be bothered to read the article because your opening pictures is a Mayfly, not a mosquito.
    You may want to address that issue. It’ll lend an air of research, knowledge and professionalism to your work.

    John, August 8, 2014 at 4:07 pm
  357. I can be in a crowd, say at a picnic and i will get eaten alive while others suffer no bites. This happens all the time, so much so that i am hestiant to engage in outside activities and repellants have no affect. Still haven’t a clue how to protect myself. These bites hurt and they ruin your skins!!! I need a defense!

    The Vanilla Godzilla, October 25, 2014 at 10:24 am
  361. Whaaaaaaaaaatt? I’m Blood Type A and I usually keeps on getting bitten by mosquitoes more than that of my sister who’s Blood Type O. It’s so frustrating especially during the cold season that mosquitoes are hiding inside the houses and dark places. I’m always the poor one in my family. I have to put ointments everywhere in my body :/

    Chess Risette, December 5, 2014 at 8:52 am
  362. Well, my blood type is B+ positive and get bitten more than others. I often see mosquitoes hovering around me more. It’s messy to use the creams and my main remedy is with a mosquito net that is pretty simple and more practical to me. And yes the ones that attach me inside the net sometimes, face the wrath of my chinese mosquito bat!!

    Vijayan Aravamudhan, December 13, 2014 at 10:22 am

    Ryan, December 23, 2014 at 11:27 pm
  364. It really is just coincidence rather than blood type It is possible that it was just where you were standing at that moment of popularity of the mosquitos at that time chemicals in blood are tremendous to I get bit even in las Vegas by mosquitoes they itch really bad . Blood type has nothing to do with this. I get bit Simi alot body temputure average of 97.2F my blood type I think is AB+ Positive.

  365. I have just read the article, but not all the comments.
    My wife was a rare blood type and had terrible trouble
    with Mosquitoes until she was diagnosed with Leukaemia
    they never went near her again. Can they detect
    if the blood is not right?

    There is greater reason for that you simply

    Debra, June 1, 2015 at 7:48 am
  369. Blood type has nothing to do with bite ratio. My wife and I are both O+ she doesnt get bitten I do. Body temp also out. Both reading same temp, difference between us besides different sexes is I have an extremely high fast moving immune system due to pollen reaction. Being +/-or A,AB,O seems little in bite ratio from reading all the articles seem little to no effect. Maybe we are all looking into this far to much. It is what it is. Chemical inbalance within each of us. Blood impurities she gives blood 4 times a year and it is accepted, I do not give blood as test results came back as not being clean enough to use. No I do not have aids or anything harmful to me it is just not clean enough. Look at the countries reports come in from hygiene not always great and temps are high thrieving areas for insects to increase in. Oh the bloke from the army, hydration theory is out I drink 1 pint water a day my wife 4 pints water a day I still get bitten. You all want possible solution for going out without getting bitten, simple move to north pole insects dont like extreme cold

    Rich, June 18, 2015 at 1:23 pm
  370. I’m not buying the blood type causing more bites. My DH is Type O- and never gets a bite. I am A+ and get bit on a regular basis. Neither one of us smoke or drink.
    I will say that I noticed something interesting this summer though. I have been using different soaps. My normal soap was Irish Spring. Of course I always got bit. I changed to a citrus soap, and I didn’t get bit. I ran out of my citrus on vacation and used a coconut soap, and I got bit again. I also tried an Almond soap and got bit. I finally went back to the citrus, and I don’t get bit. I can’t tell you everthing that attracts mosquitoes, but I can definitely tell you what can help prevent them from sucking your blood….citrus soap. Hope it works for others as well!

    Stephanie, June 19, 2015 at 4:01 am
  371. I’m type B+ and it seems every day about 2-3 more bites get added to my collection. While other folks say they haven’t seen a mosquito since moving to southern California, I’m a native that’s walking proof that they’re around.. I always say the bugs want happy blood so they go for be positive blood heh

    Amber, July 9, 2015 at 10:03 am
  372. I believe in the temperature points. But u know tastes of meats are not always the same-some are sweeter-even same fruits can differ in taste. When go to buy items or even fishes,chickens…at point and kill you make a choice-select the one that attracts you. So mosquito goes to the sweeter person. Bees do go to flowers that produce more juices to aid formation of honey-all animals have a level of intelligence

    Ekeh kelechi Emmanuel, July 19, 2015 at 3:20 pm
  373. Ever since I can remember I’ve had serious reactions to bee stings and mosquitoes. After I had my second child my reaction to the bites we’re not as bad, but I still get eaten alive.

    Kat, July 29, 2015 at 10:55 am
  374. why do mosquitos bite us

    drexel, August 8, 2015 at 8:29 am
  375. my answer to this post is>>>>>>>First of all, it’s not in your head. Mosquitoes really do prefer some people to others, says Dr. Jonathan Day, a medical entomologist and mosquito expert at the University of Florida. And that time your grandmother told you your skin was just sweeter? There’s some truth to that, Day says. “Some people produce more of certain chemicals in their skin,” he explains. “And a few of those chemicals, like lactic acid, attract mosquitoes.” There’s also evidence that one blood type (O) attracts mosquitoes more than others (A or B).

    Unfortunately, your genes dictate your blood type and the chemical makeup of your birthday suit. Genetics also determine several other factors that could make you an object of blood-sucking affection for your local mosquito population, Day says. Maybe the most important: Your metabolic rate, or the amount of carbon dioxide (CO2) your body releases as it burns energy.

    Mosquitoes use CO2 as their primary means of identifying bite targets, Day says. Why? “All vertebrates produce carbon dioxide, so what better way could there be for a mosquito to cue in on a host?” And while it’s true that you can moderate your metabolic rate through diet and exercise, you can only change your metabolism so much, Day says.

    “Pregnant women and overweight or obese people tend to have higher resting metabolic rates, which may make them more attractive to mosquitoes,” he explains. Also, drinking alcohol or physically exerting yourself raises your metabolic rate—and also your appeal to winged biters, he adds. (Exercising before grabbing a beer and heading outside = asking for trouble.)

    While CO2 detection is the primary technique mosquitoes and other blood-sucking bugs use to spot hosts, they also rely on secondary cues to differentiate you from cars, decaying trees, and other CO2-producing objects. And you can control some of those secondary cues, Day says.

    For example: Dark clothing is more attractive to mosquitoes than light oufits. Why? “Mosquitoes have problems flying in even a slight wind, and so they keep close to the ground,” Day explains. Down there, they spot hosts by comparing your silhouette to the horizon. Dark colors stand out, while light shades blend in, he says. At the same time, lots of motion distinguishes you from your surroundings. So if you’re moving around a lot or gesturing, you might as well be shouting, “Hey, mosquitoes! I’m right here, ladies!” (Only the females bite, Day says.)

    drexel, August 8, 2015 at 8:35 am
  376. I think it probably has to do with a person’s body PH rather than their blood type. The PH of your blood would actually change the way you taste to the mosquitoes, fleas, etc. I’ve noticed that on the rare occasion I’m bitten by a mosquito, it doesn’t swell up as much if I eat healthy, but as soon as I start eating a bunch of sweets- BIG ITCHY MESS!

    Veronica, September 1, 2015 at 3:03 pm
  377. Hi I’ve never bin bitten and I honestly think it’s because I’m vodka drinker I no that sounds bad lol but I really believe it’s true x

    Melissa webb, September 10, 2015 at 6:00 pm
  378. I’m always the one getting bitten. I am trying home remedies. So far, nothing is working.

    Carol, September 24, 2015 at 9:28 pm
  379. I worry about using deet products on a daily basis so I am trying to prepare something safe to apply to my ankles. I will post here if successful. Here is what I plan to try: rubbing alcohol applied to ankles, vinegar applied to ankles. Also wondering if I should buy a dog’s flea collar and wear it on my ankle. Has anyone tried this and is it safe?
